Anki Search by Number of Again

I have slaved over perfecting my Anki settings. I spend about 3-5 hours on Anki every day. I started doing Anki religiously in November of 2019, which is virtually 2,300 hours on Anki. That'due south crazy. I know it's crazy though. And so If I am this crazy, and spending this much of my precious life with Anki, I meliorate be using it as best as I can.

If you lot want to merely skip to screenshots of my settings just click here.

I take found the settings, that I call up, work all-time. These settings avoid "Ease Hell," optimize memory within a i-ii yr time period (the first two years of medical school), and prevent excessive card buildup. As well, I take tried to tinker with these settings for understanding as opposed to memorization . I want to empathise, not memorize, these cards.

In this post, I will evidence you every i of my Anki settings and the explanation backside each one as well.

If you are completely new to Anki in Medical school I accept a post on setting upwardly Anki with the AnKing for the first time here.

Full general Settings

Equally a disclaimer, these are only the settings I have found to work all-time for me in medical school. These may not be optimal settings for learning other things such equally a new language or for how you larn individually. There are no "perfect" settings. Yous should read this post to get a good understanding of what the Anki settings and algorithms hateful and "good" settings to starting time off with. Then, play around with them to lucifer your learning fashion.

My settings are adjusted from the AnKing'south, Conaanaa'due south, and MedShamin's guides. I noticed, about 6 months in that certain settings weren't working out as well for me, like the "once more" setting and max-time interval. I adjusted those to piece of work for me. This is a long, merely I think fairly helpful post. Buckle in.

Let's commencement with preferences.

To access preferences go to:

Top Toolbar → Anki → Preferences

Basic

The only matter worth mentioning here is "Night Mode." This setting makes my deck have a gray groundwork normally with white text. Night mode means certain things about my Anki will look different, equally shown on my Anki beneath:

If you want a guide on how to customize your Anki background click here.

Scheduling

This is the most important section in preferences.

"Show next review time above respond buttons" is the departure between this:

and this:

I think information technology's better to go out it enabled so you tin monitor to see if Anki is doing anything funky with your review times. Also, it'due south beneficial to know how far in the future your cards are being pushed if you have an exam coming up.

For example, my Pace 1 exam is in 2 months, so I know if I come across "iii months" on the "good" button, I better know that card considering I won't be seeing it again earlier I have my exam.

I leave "show remaining bill of fare count" unchecked. I feel that information technology is distracting and makes information technology more than about smashing through the number of cards than understanding the information.

I detect myself staring at that number.

The only other one worth mentioning is the two.i scheduler beta. I enable this setting. Some benefits of this (a full list of changes tin be constitute hither):

Reviews show upwards in random order (This is the near important modify, in older versions of Anki reviews would show up in order. I do non think that is best for reviewing information for an exam. How volition we be tested, in social club? Probably not, allow'southward mimic exam mean solar day as much as possible and accept our reviews evidence upwards in random gild).
Filtered decks piece of work much better (cards stats don't reset when building or deleting decks)
Suspending/burial cards doesn't affect learning steps
Learning cards at present have a "hard" button, this is just the average of your "again" and "expert" learning pace. And so my "once again" pace is 15 minutes and my "expert" step is ane day and so my "hard" step is ~12 hours.

The adjacent setting is the order of cards to be shown. I select "Evidence new cards subsequently reviews."

This is because I desire to review all of the information that settled in my brain overnight first. And then I will larn whatsoever new cards leftover from the day before. Then I will learn the new content for today from third-political party content, unsuspend those new cards, so study them.

You tin can cheque out my daily study routine here.

Finally, I accept the "new mean solar day" first at iv am. This is the time at which the "next twenty-four hours" is registered past Anki. That ways cards that are destined for the adjacent agenda day appear at iv am that twenty-four hours. If you study tardily into the night or start studying really early in the morn, you lot might want to change this setting. I am never upwardly by 10 pm studying, and never up before 5 am. So I set it for iv am.

The final setting worth mention here is the acquire ahead limit. This ways if Anki pushed a card 15 minutes into the future, equally it what happens for me when I striking "over again," if the "learn ahead limit" is xv minutes, I could review information technology now (0 minutes afterwards striking "once again"). However, if it is set up at 0, equally mine is, I have to wait that fifteen minutes before I run into this card.

I would never alter this setting unless y'all are trying to get through these cards earlier bed, or need to get through the cards in a curt corporeality of fourth dimension for some reason.

When you mess with this setting you lot are messing with the algorithm. We want to minimize that every bit much as possible. We like the Anki algorithm.

The final setting seems like Anki's endeavor at a Pomodoro built-in timer, or some sort of timer. It isn't that great. It merely will tell you how many cards yous've reviewed later a certain amount of time.

If I had this equally "1 minute," it would tell me how many cards I reviewed afterwards one minute.

If you striking "Cease," it takes you out of the deck to the deck browser. If you hit "Proceed" you enter into some other cycle. I would disable this. There are better Pomodoro timers. The one I employ is the Be Focused – Focus Timer available on the Apple store. Some other fun option is the Wood timer for your phone. I talk about these in my mail service here.

Network & Backup

Non much to mention hither. I just accept the "on next sync" disabled. Every bit I don't like forcing changes in any direction. These settings will automatically sync your Anki occasionally, with images, and automatically sync whenever you lot open up or close Anki.

Deck Settings

Now we are on the almost important part. The deck settings are going to be what defines how ofttimes you run into your cards and, therefore, play a large part in your retention of these cards.

Background Data

If you want to just skip to the images of my settings click here.

Learning Anki cards can be separated into two phases. "Learning" and "Graduated."

When you showtime unsuspend or add a bill of fare it is a new bill of fare in the "Learning" phase.

Afterward you lot complete a certain number of "learning steps" (similar hitting "practiced" at solar day 1 and hitting "adept" again at twenty-four hour period 3), your card is "graduated." Dislocated? I was too, let'due south explain information technology a fiddling amend:

Endeavor and ignore the specific settings, for now, focus on the "Steps." The "Steps" is your "Learning" phase. I want to requite a background of what this all means.

This means, when you are learning a new card you will see information technology at set intervals depending on what you select:

If you don't know it and hitting "over again," the carte du jour will be shown to you in 15 minutes.
If you do know information technology and hit"expert," the card will exist shown to yous in 1 twenty-four hours (1440 minutes is the number of minutes in one day)
On day 2, if you still know it and hit "skilful," the card will be shown to you once again in 3 days (4320 minutes is 3 days) and the bill of fare is graduated.
On day six post-learning, the card is graduated and is subject to the normal Anki algorithm (which volition be explained shortly)
If at any point in this "learning stage" you lot striking "easy" the card volition immediately be graduated and sent 8 days into the future. This is the "Piece of cake Interval."
If at whatsoever signal in the "learning phase" y'all hit "again," the carte du jour is sent back to its first "learning stride" and you will meet that card again in xv minutes.

So what is the "normal" algorithm of Anki? And how are our graduated cards treated differently? I'yard glad you asked.

Usually, when you hitting "good," it is ii.5 10 the current interval. But this only applies to graduated cards . And then if your graduated card was at a 1-day interval, and y'all hitting "good," the card will testify up at 3 days, so if y'all hit "proficient" once again, at 7 days, and so on…

But there are more buttons, every time y'all hit one of those buttons, "again," "hard," "good," or "like shooting fish in a barrel," Anki applies a different algorithm on that card to determine the next time yous will see that card.

There are many new and confusing terms higher up, don't worry about that yet, I will explain all of them as the post goes on. Start by looking at "Lapse."

A lapse is a card you didn't know, that'south why you lot hit "again," and this carte will enter a new "re-learning" stage. This is what happens whenever you hit "again." What that ways is that you lot will have to relearn that information at a pre-set interval (in settings that we will get over later) before yous can "re-graduate" that card.

For instance, my lapse settings are:

And then, if I hit "again" on a card that was at an interval of 100 days I would be shown the carte in 20 minutes. Then, if I striking "good," I will be shown that card in 1 day. Then, if I hitting "proficient," once again I will meet that card in 10 days. That carte has "re-graduated."

Why ten days? Well, my "new interval" is set to 10%. And then this means, when I lapse or striking "once again" on a menu, and I become through my 20 minutes and ane-mean solar day re-test, the card is put back on the schedule at 10% of what information technology was originally. So it was originally 100 days, and then now it is x days.

Now for the "hard" part.

The "hard" button is fairly simple, but what is this new word, current interval?

The current interval is the interval of the bill of fare is right now, so let's use the 100 days instance. And then the current interval is 100 days, which means I saw this card 100 days ago.

1.two is exactly that, 1.2.

Interval Modifier is a static number you fix in the settings. For at present, I will just tell you I leave that at 100%. This means it does nothing as 1*1=i as far as I know.

And so, if we hit "difficult," the card will testify up in 120 days.

Now, onto the "expert" part.

Electric current Interval nosotros know and Interval Modifier we know, only what is this "Ease Factor?"

The Ease Factor is a unique characteristic of every card. It is initially set at 250%. I recommend never changing this. Importantly, nevertheless, Ease Factor will change specific to the menu you are doing as y'all answer "again," difficult," "good," or "easy." So when we take a fresh new graduated carte, that has left the learning phase, that bill of fare is at an Ease Gene of 250%. Every time nosotros do that card, yet, depending on our answer, the ease gene is inverse every bit shown below:

And so using our aforementioned example of 100 days, if nosotros hit "good" nosotros volition see the card at:

Electric current Interval (100 days) * Interval Modifier (100%) * Ease Gene (250%)

So we will run across that card in 250 days.

If we hit "hard" or "again" we would see that card at the interval described earlier, BUT, our Ease Factor for that bill of fare is now inverse. If we striking "once more" the ease factor is now 230%, if nosotros hit "hard," the Ease Gene is now 235%.

Why is that? Well our Ease Factor is now 230%, and so instead of:

Current Interval (100 days) * Interval Modifier (100%) * Ease Cistron (250%) = 250 Days

it is:

Current Interval (100 days) * Interval Modifier (100%) * Ease Gene ( 230% ) = 230 Days

I hope this makes sense, as an agreement of this is important for the settings I have.

Finally, we are on to the "Piece of cake" part.

What is "Easy Bonus?"

Easy Bonus is merely a static number nosotros can ready in the settings, just like Electric current Interval, that is multiplied to the final interval.

Easy Bonus is normally gear up at 130%.

Ok, well done if you got through that. I recall that data is necessary if you want to get the well-nigh out of Anki and empathize my settings.

Now, onto the good stuff, onto my settings.

New Cards

To admission this folder become click on the cogwheel next to your deck. I like to continue all my decks the same type, "Default." As you can see all of my decks are nether the "AnKing."

So, this is the important part, what are the steps? Well, we talked about it earlier right. Steps are when your cards are in the "Learning" phase. Hither is what I didn't mention earlier when your cards are in the "Learning" phase, they are prophylactic from Ease Factor modification.

Once cards are "graduated" they are afflicted by the Ease Factor.

How do nosotros "graduate" cards? Well if we go to the settings of Steps and Graduating Interval, once we hitting "skilful" on our final learning step, the card is graduated and we volition see at our "Graduating Interval."

Run into New Card → Hit "good" → Nosotros run across the card 1 day later → We striking "expert" → We now see the card 3 days subsequently → we hit "proficient" → the card is now graduated and nosotros see it half dozen days subsequently.

Ok, let'southward come back to that mystical Ease Factor. Then, while we are doing our learning steps, our Ease Factor is unchanged. That ways that whatever "agains," or "hards," we select during the "learning phase," up until that final learning footstep (iii days) DOES Not change the Ease Factor.

Then, this means we tin can hit "again" on our learning cards all we want upward until that last learning step (at day 5 post-learning) without affecting the Ease Factor.

Why is this important? Well, when we are first learning our cards things are still just first to make sense. It may exist a tough day that day, or perhaps your brain is being funky, or maybe you just oasis't learned that topic in a lecture that calendar week however, or maybe your First Help book is angry with you for not taking out the trash, common medical pupil problems.

After nosotros hitting "again" on a Graduated card half dozen times our Ease Factor reaches a minimum of 130%. If this happens to too many of our cards, we enter something called "ease hell."

We want to avoid "Ease Hell." Nosotros want to avoid it considering we will be seeing too many cards besides oftentimes making Anki unmanageable and inefficient. Anki is an astonishing piece of software, merely it's exactly that, software. If nosotros go out the settings as is we are more than than likely to enter ease hell.

How I decided on my settings:

All of the points higher up hateful that we exercise non want to be playing with the well-researched algorithm for maximizing retentiveness that decided on this 250% number, which is why we want some jerk room in the learning phase (the specifics of the algorithm research was kicked off by Ebbinghaus in 1885, adult upon in 1972 by German Scientist Sebastian Leitner in 1972, and further developed past SuperMemo most recently^1,ii,3. If y'all want to bank check out my full mail service on the reasoning behind spaced repetition go here).

This is where my individual preference comes in, and you will, and should, modify these numbers to maximize your gains and personal preference.

In coming up with my learning steps I referenced two "gods" in the field of medical school Anki and that is the AnKing and Conaanaa.

AnKing'due south Steps: 25 → 1440 (1 Day) → Graduated (three Days)

Conaanaa'southward Steps: fifteen → 1440 (1 Mean solar day) → 8640 (6 Days) → Graduated (15 Days)

Mentionable Option (reddit user – anbu5000): 15 → 1440 → 4320 → 8640 → Graduated (15 days)

My Steps: 15 → 1440 (i Day) → 4320 (3 Days) → Graduated (six Days)

In general, I fall somewhere between the AnKing and Conaanaa's settings. AnKing is harsher, emphasizing high correct rates over more time spent, "put in the extra 30% time for the v% gains." Aiming for mid to loftier 90s % success charge per unit.

Conaanaa's settings are longer-term, with still high retention, with between 80-xc% success charge per unit. His justification being the more steps you add together the safer you are from messing with the Ease Factor and, therefore, "Ease Hell."

My justification for my settings:

We want to, eventually, start messing with this Ease Factor. This is what helps differentiate specific cards that are more than challenging to us or easier to u.s.a..
Nosotros are trying to maximize our retention in 1-2 years, non 5+ years (I will adjust my settings towards Conaanaa's subsequently Step 1)
In medical schoolhouse, nosotros may be quizzed on something nosotros but learned that week that's why I like to run across that card at least twice inside 5 days.

Many internet sources support Conaanaa's eighty-ninety% target, however, I had a hard fourth dimension finding peer-reviewed academic journals in support of this specific number of 80-90%⁴.

In my opinion, the AnKing makes a good point that nosotros want to be above 90% for maximizing our Stride 1 score, however, I think aiming for the mid to high 90s makes the number of cards you have to practice unmanageable.

So what did I make up one's mind? I want to aim for the loftier 80s, and then maybe 88-ninety%. This combines those 2 ideas. These full general settings got me in that ballpark, simply, really, I haven't adjusted them for over a year. To fine-tune my mode upwardly to xc% I adjust my interval modifier, which, call up is practical to all cards. I will talk most that afterward, simply rapidly, if my success rate is also low I decrease my interval, seeing the cards more oftentimes. If my success rate is as well high, I increase my interval, seeing the cards less ofttimes.

At present (thankfully) things get a little more straightforward. Let's talk about what "Easy Interval" ways.

All information technology ways, if that at whatever betoken during the learning stage, you hit "easy" the carte is immediately graduated and shown to y'all however many days subsequently you lot select. I chose 8 days because my graduating interval, of 6 days, is a 24-hour interval shorter than normal equally if you applied the normal Anki algorithm my graduating interval should be 7 days. Only, remember, nosotros want high retentiveness and exposure in that first time seeing that menu, which is why I fix information technology at 6 days.

If you are hitting "easy" you actually know that carte. I rarely hit easy, and so when I do it'southward for proficient reason. I bumped it a day past the normal, so viii days.

Adjacent is "Starting ease," remember we don't want to impact this!! This number was decided upon after many (professional person) experimenters decided upon information technology^1-three. I keep mine at the default 250%.

Next, is "Bury related cards until the next 24-hour interval." I enable this. This makes cards that are related, as shown beneath, be separated past 1 day.

Every bit discussed with doing reviews in random gild, I like to exercise my new cards in random social club likewise. This setting is not equally of import as doing the reviews in random order, but have constitute it helps over again with avoiding the trap of memorization as we tin think our new cards past the club that the information is being presented in as opposed to actually understanding the information.

What this does is if you lot have a menu similar:

ii + 2 = 4

with a cloze deletion of "2" and "4," the carte du jour would appear to you twice equally:

two + __ = 4

ii + two = ___

These ii cards could appear on the same twenty-four hour period, and if they are new cards, and you had this setting disabled, they would appear on the same day. I don't like that. I feel like I will just think the reply of "4" from doing the card earlier instead of understanding that ii + ii = 4.

A major gripe I have with Anki is it too piece of cake to fall into the trap of memorization, most of my settings are trying to avoid that trap past emphasizing understanding.

How do we emphasize agreement? Well, I think, we avoid using short term memory as much as possible. This is why I have my lowest learning step at 15 minutes and why I have this setting enabled.

We are washed with New Cards! Well washed.

Reviews

For reviews, the most important setting is the start ane. Again, we don't want to mess with the Algorithm at all. If cards are being pushed to the next day because we maxed out our reviews, we are messing with the algorithm.

Set your max reviews to 9999 and do all of your reviews, every day.

Next is Like shooting fish in a barrel bonus. I set Easy bonus to 140%.

Piece of cake Bonus is fairly straightforward, if you recollect this image:

Personally, I rarely hit "Easy." And so when I practise it means that card was actually easy for me. I just bumped the number upwardly from the default "130%" to "140%." This isn't groundbreaking, information technology just works well for me.

Next, nosotros are onto another very important particular, however, i that is easier to understand, the interval modifier. I have changed this number a couple of times, correct now, I am happy with it at 100%.

If you lot are striking "easy" and "once again" and "hard" at the perfect times, perchance, y'all tin avoid changing this number at all. Notwithstanding, sometimes, yous are simply seeing cards too often or likewise infrequently. Irresolute this number volition change all graduated menu intervals as you lot are doing your Anki cards. Let's look at an instance assuming you hit good with your Interval Modifier at 100%.

Now if your interval Modifier is l% .

At present let's compare the 2 in the long term.

Every bit you tin run across this makes a big difference, ok, I think you know what it does, now allow's talk virtually when to change information technology. If the following is likewise confusing/scary for you, it's ok, just leave it at 100% and everything should be fine.

I spoke near this earlier, just, in general, I like to aim for a Success Rate of the very high 80s. My reasoning is that I want to score well on Footstep, we tin score well by having a high success rate, nonetheless, every bit we effort and button that success charge per unit up the work exponentially increases (something like 30% extra work for 5% gains). Now, that'south ok for me, to a signal. I tried pushing over the 90% hump and my menu count got besides high. Also, many other people seem to emphasize an 80-90% success rate. So, like finding merely the right temperature oatmeal, I decided on trying to hit equally close to 90% without passing it. I'm doing pretty well with that.

To get this information just download the true retentiveness app → restart Anki → "Shift-Click" Stats on your deck browser.

What I would do, over the past ii years, is monthly I would check up on this number. If I felt I was seeing likewise many cards, and maybe pushing past 90%, I would increase my interval modifier past 5% to encounter the cards farther apart.

If I felt I was seeing also few cards, and my retentiveness rate was dropping to the mid-80s, I would decrease my interval modifier by five% to encounter the cards more frequently.

Then what do I advise for you? Well, I am pretty happy with my electric current setup, I don't recall information technology's a bad identify to aim for at all. Play with that interval modifier, slowly, and carefully and don't rely on statistics from one twenty-four hour period or even one week.

Next things to talk about the maximum interval.

I will defer to a bang-up mail past reddit user u/nicolascuri, merely he says nosotros should never cap our max interval. I agree with him. Unnecssary repetitions are exactly that, unnecessary.

If yous make this number too small like 3 months, the number piles upwards (yellow line). Interestingly afterwards 6 months (pink line), for me, the increasing of the max interval doesn't make of a difference via this sumaltion. 1 year is the orangish line.

This is using the Anki simulator app which can be accessed hither

I recommend setting a max of at least half-dozen months (180 days) and possibly higher if you want. To exist safe, I will officially recommend 240 Days (8 Months) for the first two years of medical school.

Next, allow'southward talk nigh the hard interval.

I discussed this earlier, but this is merely a static number that applies whenever you striking hard on a graduated bill of fare. Don't alter this. I rarely hit difficult. I don't encounter any reason why you desire to adjust this. Just for the sake of spaced repetition…

I have bury related reviews until the next mean solar day enabled.

As spoke most before, I want to avert memorization. Let'south apply the "burying" rule to reviews (on graduated cards) every bit well as "learning" (on new cards).

We are on the home stretch now! But lapses to do and nosotros are washed.

Lapses

Lapses are what happens when we go a card wrong. If you remember how I described information technology earlier:

When you get a card wrong it enters "relearning." It is basically the same as "learning" a card except when yous graduate the card its adjacent interval is determined by your new interval %. I put one less interval on the "relearning" phase because I already learned it.

I take my lapse setting at x% because when I become a carte incorrect, I usually really don't know it. I almost need to entirely relearn that card. This is the way I designed my settings. I don't have it at 0% because that makes the card load too loftier, and, usually the bill of fare will prove up besides frequently for me.

I experimented with the 80% lapse percentage merely information technology was manner too loftier. I would relearn a card with those steps of 20 minutes and 1 day, and so if a carte du jour had an interval of 100 days, I would see information technology again eighty days after. It was definitely not solid plenty in my heed to exist showed 80 days subsequently, so, what I noticed, is I would become to 80 days with these cards and I would inevitable striking "again," with no understanding of the card whatsoever.

I suggest you set it at ten-xxx%. I similar the 10% number.

Oftentimes, even so, 10% of my current interval of a bill of fare drops the next interval to below a day. That's where this setting comes in:

This means, that say I accept a card with an interval of 10 days, I get this card wrong. ten% of x days is 1 day. I don't want to be reviewing this card at i day → ane day, that is silly, and confronting the algorithm, so I don't.

Now, let's talk near leech threshold and leech action.

What this means, is if you hit "over again" 8 times on a graduated card the card volition exist tagged equally a leech.

I exercise not think the "suspend" setting is a good idea. Nosotros desire to do really well on Footstep 1, this means nosotros want to larn these cards that are a struggle for us, non push button them to the side.

The other thing to notation is that if you have hit "again" 8 times your bill of fare has hit the floor of the Ease Factor. So your Ease Cistron is at 130%. That'due south OK though, call up, we adjusted for the learning phase with our learning steps. And so if the Ease Factor is at 130% now it is meant to be in that location, you need to look at this carte, and you need to keep looking at this card.

I tin can track my leeches and fourth dimension spent on private cards, about monthly, I will check the cards that are taking me the most time and accept some fourth dimension to learn the facts that are my sticking points.

side notation: if you want to track your leeches, and the time spen t on every leech, I suggest you download the advanced browser app, which will permit you customize your browser to sort for "time spent" on certain cards.

General

These settings are straightforward.

If I become up from my desk, or look at a card for longer than three minutes, Anki assumes me as "afk" and ignores the reply.

I do not like to show answer time as information technology is distracting.

On the few cards that have audio, I similar that to play immediately afterwards I answer.

Fuzz Factor

As an extra piece of data, Anki has a built-in "Fuzz Cistron." What this means is that, on all cards, a unlike interval volition be applied to cards from 80-120% of what the interval would be without the fuzz factor regardless of what button you press.

So when you press any push button, Anki may give that menu an interval of anywhere between 80 and 120 days. This isn't such a huge difference that it's messing with the Anki algorithm. This is but put in identify so when you lot introduce new cards, you won't have to review all of them on the aforementioned solar day.

Honestly, for our situation, this doesn't make much sense as we are doing new cards pretty much every day, but, if, for example, yous did TONS of new cards on ane day, and not so much on another solar day, this would aid balance the load.

If anyone has used load balancer (which I don't recommend using because load balancer actually does mess with the algorithm), this built in function is like that.

Final Tips

You must be honest with yourself. "Tip of the tongue" is not good plenty. Hit "once more."

If a card is showing upwardly also much I just striking "easy." If this is happening across the board I call up about changing my interval modifier.

I continuously edit, add images, and exercise the Feynman Technique with individual cards.

Otherwise, we did information technology! Thanks for reading and I promise this was helpful.
