Anki for Step 1 has a reputation problem.
Half the internet tells you it’s the only way to pass. The other half tells you it’s a time-sucking trap that burns students out before dedicated even starts. Both sides have a point — and neither is fully right.
Here’s the honest picture: Anki is one of the most powerful retention tools available for Step 1 preparation. A published study found that for every 1,700 unique cards introduced into a student’s Anki deck, scores on USMLE Step 1 increased by approximately one additional point. With the AnKing deck containing over 30,000 cards, the theoretical ceiling is significant — but theoretical ceilings mean nothing if you abandon the deck by week three because you’re drowning in 800 daily reviews.
This guide tells you how to use Anki for Step 1 in a way that actually works — which deck, how to set it up, how many cards per day, how to integrate it with your other resources, and what to do when reviews pile up. No fluff.

👉 Check Your NBME Score NowWhy Anki Works — And Why Most Students Use It Wrong
The science behind Anki is genuinely solid. It’s built on two evidence-backed principles.
Spaced repetition: Cards are shown to you at increasing intervals — right before you’d forget them. This dramatically reduces the time needed to maintain long-term retention compared to re-reading the same material repeatedly.
Active recall: You’re forced to retrieve the answer from memory, not recognize it from a list. Recognition (reading a fact) and recall (producing it under pressure) use different cognitive processes. Step 1 tests recall. Anki trains recall.
The problem is not the tool — it’s the usage pattern. Most students who fail with Anki make one of two mistakes:
They start too late and add too many cards too fast. Starting Anki two weeks into dedicated with the intention of doing 400 new cards per day to “catch up” is a fast path to burnout and abandonment. The math doesn’t work — new cards compound into due reviews faster than most students expect.
They do Anki instead of UWorld, not alongside it. Anki is a retention tool. It keeps facts accessible after you’ve learned them. It is not a learning tool for new concepts. Students who do Anki for 4 hours and UWorld for 1 hour have their priorities backwards.
The correct mental model: Anki is the system that keeps your First Aid knowledge from decaying. UWorld is where you build the clinical reasoning to apply it.
Which Deck Should You Use in 2026?
The answer is straightforward: the AnKing Step Deck.
It’s not even close. The AnKing Step Deck contains over 30,000 cards, is trusted by more than 100,000 medical students, is continuously updated through the AnkiHub collaboration platform, and is tagged to virtually every major Step 1 resource — First Aid, Pathoma, Boards & Beyond, Sketchy, UWorld, and more.
The tagging system is what makes it uniquely powerful. Every card is tagged by organ system, subject, and resource. This means you don’t study all 30,000 cards at once — you unsuspend and review only the cards relevant to what you’re currently covering. Renal week? Filter to renal tags. Pathoma cardiovascular? Unsuspend those cards specifically.
What happened to Zanki? Zanki was the community deck that started modern USMLE Anki prep, with roughly 25,000 cards built from First Aid, Pathoma, and Sketchy. It’s no longer maintained as a standalone deck — its cards have been absorbed into AnKing, where they continue to receive updates and corrections. If you’re searching for Zanki in 2026, download AnKing.
Do you need other decks? For most students, AnKing is sufficient for Step 1 core content. Some students add the Pepper Sketchy Micro/Pharm deck if microbiology and pharmacology are specific weak points, since Pepper uses visual mnemonic-style cards specifically mapped to Sketchy. If pathology is your gap, the Duke Pathoma deck is more focused.
The rule: pick one primary deck and use it deeply. Don’t download three decks thinking more coverage equals better preparation. It doesn’t. Depth beats breadth in Anki, exactly as it does in every other part of Step 1 prep.
Setting Up Anki Correctly — The Step Most Students Skip
Downloading AnKing and starting to review immediately is the wrong approach. The setup matters.
Step 1: Download Anki (free) and install the AnKing Step Deck via AnkiHub.
AnkiHub is the platform that manages AnKing deck updates and sync. You’ll need an AnkiHub account (free tier available) to subscribe to the deck and receive updates. This keeps your cards current — errors get corrected, outdated content gets updated.
Step 2: Suspend all cards immediately.
This is the step most new users miss. When you first download AnKing, all 30,000+ cards are active. Do not start reviewing 30,000 cards. Suspend the entire deck immediately using the browser function. Now you have zero active cards — and you unsuspend them intentionally as you cover each topic.
Step 3: Enable FSRS (Free Spaced Repetition Scheduler).
In 2026, FSRS is the recommended scheduling algorithm for Anki. It’s significantly more accurate than the older SM-2 algorithm that Anki used by default. FSRS personalizes intervals based on your individual memory patterns rather than generic defaults. Enable it in Anki’s settings before you start any reviews.
Step 4: Set your daily new card limit based on where you are in school.
This is where most guides give you a number without context. Here’s the honest breakdown:
- M1/M2 (pre-dedicated, building the habit): 20–50 new cards per day. This is sustainable alongside coursework and builds the habit without overwhelming you. At 30 cards/day consistently over 18 months, you’ll have most of AnKing covered before dedicated starts.
- Dedicated period: Stop adding large numbers of new cards. Focus on maintaining existing reviews and unsuspending cards for specific weak areas from NBME incorrects. If your due review count is above 200/day, hold new cards entirely until it drops.
- Final 2 weeks: No new cards. Reviews only. Protect your review habit but don’t add new material your brain doesn’t have time to consolidate.
The Daily Workflow: Where Anki Fits With Everything Else
Anki should never be the first thing you do in a study session. Here’s the workflow that actually produces results:
Morning (30–45 minutes): Anki due card reviews only. This is the maintenance phase — you’re reviewing what’s already in your deck, not adding anything new. Do this before UWorld blocks, while your mind is fresh but before cognitive load from questions has accumulated.
During study session: Pathoma + First Aid + UWorld (as described in the integrated workflow). When you encounter a concept you keep getting wrong, or a UWorld explanation contains a pearl that isn’t in your current Anki deck, make a note.
After study session (15–20 minutes): Unsuspend cards from the system you just studied (using AnKing’s tag filters to find relevant cards). Add any custom cards for concepts you specifically missed that aren’t captured well in the existing deck.
Total daily Anki time during dedicated: 45–90 minutes maximum. If you’re spending more than 2 hours on Anki per day, something is misconfigured or you’re behind on reviews — both of which need to be addressed, not normalized.
The Review Backlog Problem — And How to Deal With It
This is the most common Anki crisis. You miss a few days of reviews, come back to 600+ cards due, feel overwhelmed, and abandon the deck entirely.
Here’s how to prevent it — and how to recover if it’s already happened.
Prevention: Never miss more than two consecutive days of reviews. Even 20 minutes of reviews on a busy day is enough to prevent exponential backlog accumulation. A half-effort review day is infinitely better than skipping entirely.
Recovery when backlog is manageable (under 300 cards): Just do them. Split into two sessions if needed. Don’t add new cards until the backlog is cleared.
Recovery when backlog is severe (300+ cards): Use the “Custom Study” feature to prioritize overdue cards by urgency. Focus on cards tagged to your current weak systems first. Accept that some lower-yield cards will be reviewed late — this is okay. Perfection is the enemy of sustainability in Anki.
The nuclear option (only if necessary): If your backlog is genuinely unmanageable (500+ cards with no end in sight during dedicated), it’s better to suspend the lowest-yield cards temporarily than to abandon the entire habit. Use AnKing’s tags to identify which cards are lowest priority and suspend them. Protect the habit, not every individual card.
Should You Make Your Own Cards or Use Pre-Made?
The honest answer: use AnKing as your foundation, and make custom cards only for concepts you specifically miss repeatedly.
Making cards from scratch for 30,000 facts is not a good use of dedicated period time. The cards AnKing has already made are better than most students would make themselves — they’ve been refined by thousands of users over years.
Custom cards are genuinely valuable in these specific situations:
- A UWorld explanation contains a pearl that isn’t in AnKing and you keep forgetting it
- A specific mechanism or clinical association clicks for you in a unique way that the standard card doesn’t capture
- You miss the same NBME concept multiple times and want a targeted card for that exact presentation
The rule: custom cards should be additions to AnKing, not a replacement for it. And they should be made quickly — if making a card takes more than 90 seconds, it’s too complex and should be simplified or abandoned.

Anki for Step 1 – FAQ
Q: Is Anki worth it if Step 1 is pass/fail?
Yes — and the reason goes beyond Step 1 itself. First-time pass rates for US MD students have declined from 95% in 2021 to roughly 89% in recent years since pass/fail was introduced. The knowledge you retain from Anki-based Step 1 prep also builds the foundation that directly improves Step 2 CK performance, which is now the primary scored exam for residency applications. The evidence for spaced repetition is solid regardless of how the exam is scored.
Q: How many Anki cards per day during dedicated?
During dedicated, the focus shifts from adding new cards to maintaining existing reviews. If you built the habit pre-dedicated, your daily review count during dedicated will be 100–250 cards per day — manageable in 45–90 minutes. Aim to add 0–20 new cards per day during dedicated (only for specific weak areas or missed UWorld concepts), not hundreds.
Q: I’m starting dedicated with no Anki background. Is it too late?
It’s not too late, but your strategy changes. Don’t try to work through all of AnKing from scratch during dedicated. Instead, use Anki targeted only to your specific weak areas — unsuspend cards for the 3–4 systems where NBME incorrects are concentrated and use those tags. Don’t attempt to cover the whole deck. Depth over breadth.
Q: What’s the difference between AnKing and Zanki?
Zanki was the community deck that defined modern USMLE Anki prep from 2017 onward. It’s no longer maintained separately — all its cards were absorbed into AnKing, which has received thousands of updates and corrections since then. In 2026, AnKing is simply the evolved, maintained version of what Zanki started.
Q: Should I hit “Again” on cards I almost knew?
Be honest with yourself, but don’t be brutal. If you needed significant hints or time to retrieve the answer, “Again” is appropriate. If you retrieved it correctly but slowly, “Hard” or “Good” captures that. The algorithm needs accurate self-assessment to function correctly — hitting “Good” on cards you’re really struggling with inflates your intervals and leads to forgetting exactly what you need to remember.
Q: How do I use AnKing tags with UWorld?
The AnKing deck has a UWorld Search add-on that lets you paste UWorld question IDs directly and find the corresponding AnKing cards. After completing a UWorld block, paste the IDs of questions you got wrong into the add-on, and it surfaces the AnKing cards mapped to those specific topics. This is one of the most efficient ways to keep your Anki reviews aligned with your actual weak spots rather than a generic system-by-system schedule.
The Bottom Line
Anki for Step 1 works — when you use it correctly. The AnKing deck, set up with FSRS, with cards unsuspended system by system as you study them, with morning reviews as a non-negotiable 30–45 minute daily habit — this is the version that produces results.
The version that burns students out is trying to do 300 cards per day, starting from scratch during dedicated, treating Anki as a substitute for UWorld rather than a complement to it.
Build the habit early. Use it consistently. Keep it sustainable. The compound effect of daily spaced repetition over months is what makes the difference between knowledge that decays before exam day and knowledge that’s still there when you need it.
