The Best MCAT Anki Decks (and When Anki Is Hurting Your Score)
A 527 scorer on the best MCAT Anki decks (MilesDown, Pankow, AnKing) and the failure modes where Anki quietly costs you points.
Search “best MCAT Anki decks” and you will find roughly nine listicles that all say the same thing: here are the popular decks, here are the card counts, go download one. That advice is fine as far as it goes. The part almost none of them cover is the part that actually cost me and my students points: the ways Anki quietly hurts a score while feeling like productive studying.
I scored a 527, I run a tutoring company, and we give away free MCAT books and a free MCAT question bank. I am not selling you a deck, and I do not make anything if you download one. So treat this as an honest rundown of which decks are worth your time, followed by the section the listicles skip.
Why spaced repetition fits the MCAT (and where it stops)
The MCAT has a memorization layer and a reasoning layer. The memorization layer is discrete facts you either know or do not: the 20 amino acids, hormone functions, psychology and sociology terms, the essential equations, enzyme names, vitamin roles. There are hundreds of these, and forgetting is the enemy. This is exactly what spaced repetition was built for. Anki shows you a card right before you are about to forget it, which is far more efficient than rereading a chapter for the fifth time.
Here is the honest ceiling: that fact layer is maybe a quarter of your score. The other three quarters is reasoning through passages, data, and experiments, and no flashcard teaches that. Anki is excellent at the thing it is good at and useless at everything else. Keep that proportion in mind, because most Anki failure comes from treating a quarter of the test like the whole test.
The decks worth knowing
Five decks come up again and again. Here is what each actually is. Card counts drift between versions and updates, so treat these as approximate.
| Deck | Covers | Best for | Caveats |
|---|---|---|---|
| MilesDown (~2,900 cards) | All subjects, plus equations | Most students; a one-deck plan | The default pick; nothing fancy, which is the point |
| Mr. Pankow P/S (~2,254 cards) | Psychology and Sociology only | Your P/S add-on deck | Big for one section; unlock it by topic, not all at once |
| Jack Sparrow (~5,978 cards) | All sections, very content-heavy | Students who want depth, especially in P/S | Paragraph-length answers; some content runs beyond MCAT scope |
| AnKing MCAT (~6,200 cards) | All subjects, merged decks | Students who want heavy tagging and updates | Larger daily load; lives in the AnkiHub ecosystem |
| Aidan (~15,000 cards) | All subjects, strong Bio and Biochem | Advanced students wanting exhaustive review | Genuinely enormous; overkill and low-yield for most people |
A few notes the table cannot hold. MilesDown is the most recommended deck for a reason: it is comprehensive without drowning you, and its seven subdecks map cleanly onto content review. Mr. Pankow is the community standard for Psychology and Sociology, organized around the AAMC outline. Jack Sparrow is exhaustive to a fault, with paragraph-length answers, which is both its strength and its problem. AnKing folds several decks into one polished, tagged package but asks for more time each day. Aidan is a monument to completeness that most students should admire from a distance.
How to actually run a premade deck
The single most common mistake is downloading five decks “to be safe.” You will never finish them, and overlapping cards will bury you. Do this instead.
Pick one general deck plus, at most, one P/S deck. MilesDown for everything, Mr. Pankow for Psychology and Sociology if that section is shaky. That is the whole plan. Two decks, tops.
Suspend everything you have not studied yet. When you first import a deck, suspend all of it, then unsuspend one subject at a time as you finish that content in review. Doing amino acids this week? Unlock the biochemistry cards, not the physics cards. This keeps Anki aligned with what your brain has actually seen, so cards reinforce learning instead of introducing cold facts with no context.
Set a new-card count you can sustain every single day. This is where most plans break. Each new card you add today generates a string of future reviews, so a number that feels easy in week one can become unmanageable in week three. Do the math before you start.
| New cards/day | Days to finish a ~2,900-card deck | Typical daily reviews once ramped |
|---|---|---|
| 20 | ~145 days | ~120 to 200 |
| 30 | ~97 days | ~180 to 300 |
| 40 | ~73 days | ~250 to 400 |
If you have three months, 30 to 40 new cards a day finishes MilesDown with margin. If you have six months, 20 a day is plenty and far gentler. Whatever number you pick, the real test is simple: can you clear the reviews seven days a week? If the answer is no, lower the new count until the answer is yes. An empty review queue every morning beats an ambitious number you abandon by October.
When Anki is hurting your score
This is the section the listicles never write. Anki can absolutely lower your score, and it does it while feeling like work. Watch for these.
It becomes productive-looking procrastination. Clearing 300 reviews gives you a clean green number and a sense of accomplishment. Doing a timed passage set and getting half wrong feels awful. So students hide in Anki and avoid passages. The problem is that the test rewards the thing that feels bad. If your Anki time is crowding out practice questions, Anki is now working against you.
It trains recognition, not application. You can recite “aldosterone increases sodium reabsorption” perfectly and still miss the passage question that buries that fact inside a novel experiment. Cards teach facts in isolation; the MCAT tests them in context you have never seen. Knowing the card is necessary and not sufficient, and it is easy to mistake one for the other.
Review debt turns into a death spiral. Set new cards too high, wake up to 600 reviews, skip a day, wake up to 900, and quit. I have watched this kill more Anki habits than any other single cause. The fix is prevention: a sustainable new count from day one, not heroics in week three.
It has real opportunity cost. Every hour in Anki is an hour not spent on UWorld or AAMC passages, and after content review, passages are where the score actually moves. During your practice phase, dial new cards toward zero and keep only enough reviews to protect what you learned.
It does nothing for CARS. There are no facts to card. If CARS is your weak section, close Anki and do daily timed passages, because that section rewards reading reps and careful review, not flashcards.
How I would actually use it
During content review, Anki is your maintenance layer, not your main activity: one general deck, one optional P/S deck, suspended and unlocked by subject, at a new count you can clear daily. During the practice phase, cut new cards to near zero, keep reviews short, and spend your real hours on passages and full-lengths. If your score is stuck and you are grinding 300 reviews a day, the Anki is probably the problem, not the cure.
And you do not have to card everything yourself. Our free MCAT books cover the full content outline, our essential equations guide and system for the amino acids hand you the highest-yield recall targets already organized, and our free question bank lets you practice applying those facts the way the test actually demands. If a section will not move no matter how many cards you clear, that is a job for a tutor, not a bigger deck.
Anki is free, open-source software. MilesDown, Mr. Pankow, Jack Sparrow, AnKing, and Aidan are community-created decks made by their respective authors. Premier MCAT Prep is not affiliated with, or endorsed by, any of them.
Frequently asked questions
Which MCAT Anki deck is best?
For most students, MilesDown is the best single deck. It covers every subject in roughly 2,900 cards, it is cleanly organized, and it is not so large that it eats your whole day. Pair it with Mr. Pankow for Psychology and Sociology if that section is a weak point, and you have a complete flashcard plan without downloading five decks.
Do I need Anki for the MCAT?
No. Anki is one good tool for the memorization layer of the test, not a requirement, and plenty of high scorers used it heavily while others barely touched it. If you already retain facts well from reading and practice, you can skip it. If discrete facts keep slipping (amino acids, hormones, psych terms, equations), that is exactly the gap spaced repetition is built to close.
How many Anki cards per day should I do for the MCAT?
Pick a new-card count you can sustain seven days a week, then leave it alone. For a 2,900-card deck on a three-month timeline, 30 to 40 new cards a day finishes it with room to spare. Remember that new cards create future reviews, so 40 new a day can mean 250 to 400 total reviews once the deck ramps up. If you cannot clear the reviews daily, your new count is too high.
Is MilesDown or AnKing better for the MCAT?
MilesDown is leaner and simpler to run; the AnKing MCAT deck is larger (around 6,200 cards) with a more polished tagging and update system through AnkiHub. If you want the smallest complete deck, use MilesDown. If you want an ecosystem with heavy tagging and are comfortable with a bigger daily load, AnKing is fine. Neither choice matters as much as whether you actually do the reviews and pair them with passage practice.
Can Anki help with CARS?
Not really. CARS tests reasoning and reading, not recall, so there are no facts to flashcard. The section responds to daily timed passages, not cards. Spend that time reading full passages and carefully reviewing why each answer was right or wrong, because that habit is what actually moves the score.
