When Is It Safe to Stop Adding New Anki Cards and Just Review?

You’re probably adding too many Anki cards for too long.

The hard part isn’t starting Anki. It’s knowing when to stop adding new cards and just review without trashing your exam score.

Let me give you the clear rules I wish someone had given my classmates before they burned out three weeks before their shelf.

---

The Core Principle: Stop Adding New Cards Before You Feel Ready

You stop adding new Anki cards when the marginal benefit of new content is lower than the damage done to your daily reviews and sanity.

Said less dramatically:
You should stop adding when:

1. Your daily review load is stable and manageable, and
2. You’re within a defined window before your exam, and
3. New material is low-yield or not sticking anyway.

You don’t wait until you “know everything.” That day never comes. If your criterion is “I’ll stop when I’m not behind,” you’ll be adding cards until the morning of your exam. Then wondering why UWorld is a bloodbath.

So let’s get concrete.

Concrete Cutoffs: When To Stop Adding New Cards

Use these as default rules. Adjust a little based on how strong you are in the material, but don’t get cute and pretend your exam is “different.” It’s not.

Exam Type	When to Stop Adding New Cards	Focus After That
Pre-clinical block exam	3–5 days before	Review + practice Qs
NBME subject/shelf	7–10 days before	Review + UWorld/AMBOSS
Step 1	10–14 days before	Review + practice exams
Step 2 CK	7–10 days before	Review + high-yield QBank
OSCE/clinical skills	5–7 days before	Cases, checklists, review

Here’s how to use this:

• If your cardio block exam is in 4 days:
  Stop adding new Anki now. Review only + practice questions.

• If Step 1 is in 12 days:
  Stop adding new cards. Your life is now:

  • Daily reviews
  • Targeted practice questions
  • Reviewing missed concepts with existing cards, not new ones

Can you bend this? A little. If you truly find a huge blind spot (e.g., you realize you never learned shock types), you can add a micro-batch of 5–10 ultra-high-yield cards. But that’s an exception, not daily behavior.

---

Quantitative Triggers: Daily Numbers That Mean “Stop”

Beyond dates, there are hard numbers that should flip the “no more new cards” switch.

You should strongly consider stopping new cards if any of these are true:

• Your daily review count > 350–400 reviews consistently
  Most students collapse above 400/day long term. I’ve watched people try 600/day for 2 weeks and then ghost Anki entirely. That’s worse than never starting.

• Your review accuracy is < 80% for several days That means you’re not consolidating. You’re just pretending to work.

• Your learning queue is overflowing
  If you’re adding 50–100 new cards a day but can’t get through all your reviews, that’s not “grind.” That’s poor strategy.

• You’re repeatedly forced to “bury” or “suspend” reviews just to survive the day
  That means your system is overbuilt.

Once one of these is true, do this:

1. Set new cards/day to 0 in that deck (or all decks).
2. Commit to at least 5–7 days of review-only mode.
3. Reassess only after that block, not daily.

---

How Your Phase Changes the Rule

There’s a difference between:

• A first-year in a cardio block
• A third-year on surgery trying to survive 5 am rounds
• Someone 3 weeks out from Step 1

The “when do I stop adding?” answer isn’t identical for all three.

Pre-Clinical Blocks (MS1–MS2)

Goal: Build concepts without drowning.

Use this rough framework:

• First 50–60% of the block:

  • Actively add new cards from lectures/pathoma/Boards & Beyond/etc.
  • Keep new cards/day in a sane range (usually 20–40 per major course, maybe 60–80 total if using premade decks).

• Last 40–50% of the block:

  • Taper new adds.
  • Shift time to practice questions (NBME-style, school question bank).
  • Hard stop 3–5 days before exam: review-only mode.

If you’re still adding brand-new details from lecture slides 2 days before your exam, you’re prioritizing completeness over performance. That’s a good way to get an average score and feel miserable.

Dedicated Step 1 Study

Goal: Consolidate broad content, not hoard it.

Early dedicated (first half):

• You can add some new cards for:
  • Frequently missed UWorld questions
  • True gaps (never learned a topic, not just “forgot” it)

But if you’re using a big deck (AnKing, Lightyear, etc.), you shouldn’t be mass-creating new cards daily. You’re curating.

Late dedicated (last 10–14 days):

• New cards/day: 0
• Focus:
  • Reviews (finish your daily and do a bit of “extra” tagging weak areas)
  • Practice questions + reviewing explanations
  • Rapid passes through high-yield resources (First Aid/Boards & Beyond sketches/Sketchy rewatch, etc.)

Your brain doesn’t magically store every fact you cram in the last week. What it does do is forget stuff you already half-knew because you stopped reviewing it to chase shiny new minutiae.

Clinical Rotations and Shelf Exams

Here’s the biggest mistake I see:
MS3s adding 60 new Anki cards daily on surgery while working 12–14 hour days. Then asking me why they’re always behind.

For shelves:

• First 2–3 weeks of rotation:

  • Add a reasonable number of new cards per day (maybe 20–40, depending on time).
  • Use a premade deck mapped to resources like OnlineMedEd, AMBOSS, UWorld explanations.

• Final 7–10 days before the shelf:

  • Stop new cards.
  • Hit reviews + timed practice questions.
  • Only consider very small additions (5 or fewer) for huge conceptual gaps.

During heavy rotations, Anki is supporting cast, not the lead.

How to Transition Into “Review-Only Mode” Without Freaking Out

Most students get anxious the day they set new cards to 0. They feel like they’re slacking. You’re not.

Here’s how to make the shift cleanly:

1. Flip new cards to 0 in your active decks
   Not later. Now. That act alone lowers your cognitive load.

2. Finish your reviews earlier in the day
   Front-load your reviews so your brain is at full power. Use afternoons/evenings for practice questions and content review.

3. Add targeted “pseudo-new” exposure without cards
   Instead of new cards, you:

   • Rewatch a key video at 1.5–2x speed
   • Do rapid read-throughs of First Aid tags for your weakest systems
   • Review Anki’s “marked” or “tagged” cards for weak topics (no new ones, just re-grading)

4. Reserve new cards only for massive blind spots
   Example: You’ve somehow avoided learning nephrotic vs nephritic syndromes and your exam is in 5 days. Fine. Make 5–8 crystal-clear cards. Then stop.

Signs You Stopped Adding Too Late

If any of this feels familiar, you probably waited too long to hit pause:

• You have 1000+ reviews due and you feel paralyzed
• You start “marking easy” just to get your review number down
• You’re skipping practice questions because “I have too many reviews”
• You’re snapping at people when they say “just trust the process”

That’s not rigor. That’s mismanagement.

If you’re there now, your move is:

1. Suspend low-yield subdecks or tags (e.g., obscure micro, rare genetics) until after the exam.
2. Set max reviews/day to a realistic number (e.g., 250–300).
3. New cards/day: zero. No exceptions.
4. Use your saved time for practice questions and targeted content review.

How Strong Students Use Anki Differently

The top performers I’ve worked with have one subtle but critical difference in how they think about new cards:

They treat new cards as investments, not obligations.

Before they add a card, they implicitly ask:

• “Will seeing this 10–20 more times over the next year meaningfully change my score or clinical reasoning?”
• “Is this fact something a good question writer would test?”

If the answer is no, they don’t make the card.
They write it in a margin, nod, move on. And they score higher than the card hoarders.

By the time they hit those last 1–2 weeks pre-exam, their decks are lean and focused enough that turning off new cards doesn’t feel scary. It feels logical.

A Simple Decision Flow: Add or Stop?

Use this, literally, as your mental checklist.

Anki New Card Decision Flow

Step	Description
Step 1	Exam <= 10-14 days away?
Step 2	Turn off new cards
Step 3	Daily reviews > 350 or accuracy < 80%?
Step 4	Is this high-yield and testable?
Step 5	Dont make a card
Step 6	Limited new cards allowed

If you hit “B” on that flowchart more than once and still talk yourself into adding 60 new cards “just for today,” the problem isn’t your Anki settings. It’s discipline.

What to Do With Extra Time Once You Stop Adding

Stopping new cards isn’t about studying less. It’s about studying smarter in the final stretch.

Here’s where that reclaimed time goes:

• Timed practice blocks (UWorld, AMBOSS, NBMEs)
• Careful review of missed questions, turning them into:
  • Conceptual understanding
  • Linking to existing cards, not necessarily new ones
• Focused passes over:
  • High-yield summaries
  • Weak systems/organ blocks
  • Algorithms and differentials

Your exam performance is driven more by recognizing and applying what you know than by seeing one more obscure fact in card form.

Quick Reality Check

If you remember nothing else, remember this:

1. There is a point where new cards hurt more than they help.
2. That point is earlier than your anxiety would like it to be.
3. Your priority in the final stretch is retention and question performance, not deck completeness.

If you’re close to an exam and your gut says, “I think I should stop adding new cards,” you’re almost always right. Trust that. Then back it up with a clear plan for reviews and practice questions.

FAQ (Exactly 6 Questions)

1. What if I’m way behind on my premade deck — should I still stop new cards before the exam?
Yes. Being “behind” on a giant deck doesn’t mean you should punish yourself with new cards right before the test. When you’re inside that 7–14 day window (depending on exam), turn off new cards. Focus on:

• Daily reviews of what you have seen
• Practice questions
• High-yield summary passes
  You will always be “behind” on AnKing or similar. That’s normal.

2. Should I ever completely quit Anki in the weeks before an exam?
For board-style exams and major shelves: no. You can reduce the load (suspend low-yield tags, drop max reviews a bit), but fully quitting reviews usually backfires. Your recall tanks just when you need it. For small in-house quizzes or low-stakes exams, you can sometimes get away with pausing, but that’s not what most people reading this are dealing with.

3. What if I feel like I’m “forgetting everything” when I stop new cards?
That feeling is usually anxiety, not reality. In fact, turning off new cards lets your brain consolidate what’s already there. Keep reviews steady for 3–4 days, then test yourself with practice questions. You’ll notice performance improves, not worsens, because you’re not diluting attention across fresh, fragile memories.

4. Is there a maximum number of new cards per day I should never cross?
For most med students, sustaining more than 40–60 truly new, high-quality cards per day long term is unrealistic. You can spike higher for a short block, but if you’re routinely at 80–100+ new/day, you’re almost guaranteed to hit an unsustainable review burden later. Your goal is long-term retention, not short-term ego metrics.

5. How do I handle missed days right before an exam? Should I “catch up” reviews?
Don’t try to brute-force 800 reviews in one day to “catch up.” That’s how you turn your brain into soup. Instead:

• Set a cap (e.g., 250–350 reviews/day)
• Sort by “most overdue” or just go in order
• Anything still left undone? Accept it. Clean up after the exam if needed. Missing some reviews is less damaging than a half-burnout that ruins your last study days.

6. After the exam, do I turn new cards back on right away?
Not for that exam’s content. Once the test is done, that deck’s job is basically over unless you’re continuing it for boards. Most students:

• Take 1–3 days off Anki, or drastically reduced
• Then start new cards for the next block/shelf/board phase
  Don’t carry every deck forever. Retire or suspend what’s no longer relevant, and build fresh, efficient sets for the next stage.

Key points:

1. Set a hard cutoff for new cards: 3–5 days before block exams, 7–10 for shelves, 10–14 for Step 1.
2. Stop adding earlier if your review load is too high or your accuracy is dropping.
3. Use the freed-up time for reviews + practice questions, not more Anki creation, and your scores (and sanity) will be better for it.
