Anki Again vs Hard: What Medical Students Should Press

A practical answer-button rule for honest FSRS scheduling, partial recall, ambiguous cards, and repeated misses.

Disclosure: I build AnkiQuiz, the changed-prompt quiz tool discussed below. AnkiQuiz is not affiliated with Anki, AnKing, AnkiHub, UWorld, AMBOSS, the NBME, or USMLE. It does not replace coursework, supervised clinical training, a validated question bank, or official assessments. AI-generated questions can contain errors.

The most important difference between Again and Hard is not how unpleasant the card felt. It is whether you successfully recalled the answer.

• Press Again when you forgot the required answer, gave a materially wrong answer, or needed to see a hint or the back of the card before you could produce it.
• Press Hard when you recalled the required answer correctly before revealing it, but only with serious hesitation or mental effort.

Under FSRS, Hard is a passing grade. Anki's official guidance warns that using Hard after a failure makes intervals unreasonably long because the scheduler interprets that response as successful recall. For a medical student, the safest default is simple: forgotten is Again; difficult but correct is Hard.

This guide explains how to apply that rule to clozes, mechanisms, lists, clinical cards, and partial answers without turning every review into a debate. It complements the best Anki settings for medical school and the daily medical-school Anki workflow.

What the four Anki buttons mean

The labels are easiest to understand as one failing grade and three passing grades:

• Again: you did not recall the target correctly—a failure.
• Hard: you recalled it correctly with substantial difficulty—a difficult pass.
• Good: you recalled it correctly with ordinary effort—a normal pass.
• Easy: you recalled it correctly with unusually little effort—an easy pass.

This distinction also appears in Anki's statistics: Again counts as a failure, while Hard, Good, and Easy count as successful reviews. The official Anki deck-options guide specifically says that FSRS cannot adapt well when someone presses Hard instead of Again after forgetting.

Why Hard is not “almost wrong”

Hard does not mean “I got close,” “I recognized the answer,” or “I do not want to repeat this card.” It tells the scheduler that retrieval succeeded. If the drug, nerve, diagnosis, mechanism, or requested relationship never came to mind, that is not a difficult success. It is a failure, even when the answer looks familiar after reveal.

Why Again is not punishment

Again records useful information: the memory was not retrievable under the current cue. That may lead to relearning and a shorter future interval. It may also reveal that the card is ambiguous, overloaded, poorly understood, or dependent on wording. Hiding the failure with Hard protects today's counter at the cost of worse scheduling data.

Decide what counts as a correct answer before grading

Many answer-button problems are really card-design problems. A prompt should make the required response clear enough that you can judge it consistently.

Grade the target, not the entire back

Suppose a card asks, “Which receptor primarily mediates this effect?” and you correctly name the receptor. The back also contains a mechanism, adverse effects, and a mnemonic in an Extra field. Forgetting those unasked details does not make the answer wrong.

If those details matter, create focused cards for them. Do not silently expand the grading target after reveal.

Define acceptable precision

Decide whether the prompt asks for:

• a drug class or a specific drug;
• a broad mechanism or one molecular step;
• the most likely diagnosis or a complete differential;
• one complication or every listed complication;
• a direction of change or an exact value and unit.

The prompt and answer should agree. If “beta blocker” is too broad, the front must request the specific agent or distinguishing property.

Separate recall from recognition

Seeing the back and thinking “yes, I knew that” is recognition after exposure. It is not successful retrieval. If the target appeared only after the answer was visible, press Again.

How to grade partial recall

Partial recall needs a rule based on the card's target, not on a percentage of words remembered.

The core answer was wrong or missing: Again

Press Again when:

• you named the wrong organism, drug, structure, diagnosis, or pathway;
• you recalled a related fact but not the requested one;
• you reversed an increase and decrease;
• you omitted a qualifier that changes the medical meaning;
• you needed the first letter, image label, or answer field to retrieve it;
• you guessed correctly without being able to support the response the card requires.

A confidently wrong answer is still Again. Confidence changes how you repair the misconception, not whether recall succeeded.

The required answer was correct, but slow: Hard

Hard is reasonable when you produced the full required target before reveal but needed unusual effort, worked through interference, or hesitated much longer than normal. Use it sparingly enough that it retains a consistent meaning.

The target was correct but Extra was incomplete: usually Good

If the tested answer was correct and only optional explanation or enrichment was missing, Good is usually more faithful than Again. If the “extra” detail is actually essential, edit the card so it becomes an explicit target.

The prompt was ambiguous: fix the card

Do not force a memory grade to solve an unclear question. If two answers were reasonably possible, flag the card, choose the closest honest grade for what it actually asked, and repair the wording after the review block. Repeated ambiguity is a card-quality problem.

Medical-school examples

One-target cloze

Prompt: “Loop diuretics inhibit the ___ cotransporter in the thick ascending limb.”

• “NKCC2,” recalled before reveal: Good, or Hard if genuinely effortful.
• “NCC”: Again. The transporter is wrong.
• “The sodium-potassium-chloride transporter” when the card accepts the concept rather than the abbreviation: a pass.
• Recognition only after seeing NKCC2: Again.

Mechanism card

Prompt: “Why can severe diarrhea cause a normal-anion-gap metabolic acidosis?”

• You explain gastrointestinal bicarbonate loss: pass.
• You only say “because of dehydration”: Again.
• You give the correct mechanism slowly after ruling out renal causes: Hard may fit.

Multi-part card

Prompt: “Name the three findings in this triad.” If you recall two of three, the stated target is incomplete, so Again is the honest grade. Better still, ask whether one three-part prompt is educationally necessary. If the parts do not need to be retrieved together, split the card.

Clinical decision card

If the card asks for the next best step under stated conditions, omitting a condition that would change management is material. Grade the explicit decision target, then verify time-sensitive recommendations against current authoritative sources. Anki and AnkiQuiz do not validate clinical guidance.

Why honest grading matters more with FSRS

FSRS estimates how difficult a card is, how stable the memory is, and how retrievable it is likely to be. Your review history is the evidence it learns from. Consistently converting failures into Hard presses tells it that forgotten cards were successfully recalled.

The result can include intervals that are too long for your actual memory and misleading retention data. Pressing Again honestly may create more work today, but pressing Hard dishonestly does not remove that learning need; it delays evidence of it.

Anki's statistics guide treats Again as Fail and the other three buttons as Pass. Review monthly patterns rather than panicking over one difficult day, and optimize FSRS parameters from representative, honestly graded history.

Common answer-button mistakes

Choosing by the displayed interval

Do not press Hard because Again returns the card too soon, or Good because Hard returns it too soon. If the resulting intervals repeatedly seem unreasonable, first check grading habits, learning and relearning steps, desired retention, and whether the card itself is broken. Do not falsify the input to force a preferred date.

Using Hard to avoid a growing queue

An oversized workload is solved by reducing new-card intake, narrowing active scope, repairing expensive cards, and reviewing settings—not by relabeling forgotten cards as remembered. The guide to how many Anki reviews per day is too many covers that diagnosis.

Pressing Again for every tiny wording difference

Anki tests knowledge, not identical prose, unless exact wording is genuinely the objective. A correct synonym or equivalent mechanism is a pass. If exact language matters—for an equation, definition, legal phrase, or local assessment—say so in the prompt.

Pressing Easy because a card is familiar

Easy should reflect unusually effortless successful recall, not mere familiarity, recent exposure, or a desire to push the card away. You do not need to use all four buttons equally.

Debating for too long

Create a stable rule and move on. If a card repeatedly makes grading difficult, mark it and edit it after the session. Ten seconds of card repair later is better than a daily argument with an unclear prompt.

What to do after pressing Again

One lapse does not require rebuilding the card. Retrieve the answer, complete the relearning step, and continue. Intervene when a pattern emerges.

Ask:

1. Did I understand this before memorizing it?
2. Does the front ask one clear question?
3. Is the answer small enough to retrieve consistently?
4. Am I confusing it with a similar fact?
5. Is the card using a wording, position, or image cue?
6. Is the information still important enough to maintain?

Anki identifies repeatedly failed review cards as leeches. The official leech guidance recommends changing the presentation, addressing missing understanding or interference, or suspending low-value material. Use the medical-school leech repair workflow for a structured diagnosis.

Where AnkiQuiz fits—and where it does not

AnkiQuiz can generate questions from selected Anki text fields using different wording or formats. A small changed-prompt sample can reveal cards you pass mainly because of a familiar cloze position or memorized phrasing.

For example, after a current topic's normal reviews:

1. select 10–20 important text cards;
2. remove patient data, private notes, and protected question-bank content;
3. generate a short quiz;
4. answer before returning to the original cards;
5. reject unsupported or ambiguous generated questions;
6. repair recurring cue dependence in the source knowledge.

AnkiQuiz does not see which Anki button you pressed, judge whether a review deserved Again or Hard, change FSRS scheduling, edit cards, validate medical accuracy, or replace official practice questions. A generated quiz score should not be written back mentally as an Anki grade. Use it as an occasional transfer check, not a second due queue. The card-to-quiz tutorial explains field selection and data handling.

Questions medical students commonly ask

Should I press Again or Hard if I forgot an Anki card?

Press Again. Under FSRS, Hard means you recalled the answer correctly but with substantial difficulty. Using Hard after forgetting records a failed retrieval as a pass and can make later intervals too long.

What if I remembered only part of the answer?

Grade the explicit target. If a required part was missing or the omission changed the medical meaning, press Again. If the full target was correct and only optional Extra content was missing, the review can pass.

Should I press Again if I guessed correctly?

If the guess did not reflect retrievable knowledge the card is meant to test, press Again. If you reached the correct answer through valid reasoning required by the prompt, it can pass. Rewrite cards whose grading depends on an unclear target.

Is it bad to press Again often?

Again is not bad; it is accurate when recall fails. A rising pattern is useful evidence to inspect first-pass learning, card quality, interference, active scope, and leeches. Do not hide the pattern with Hard.

Do I need to use the Easy button?

No. Use Easy only for clearly easier-than-normal successful recall. Consistent meanings matter more than using every button equally.

Can AnkiQuiz choose Again or Hard for me?

No. AnkiQuiz does not observe your Anki review response or control the scheduler. It can provide a separate changed-prompt quiz from selected text cards, but you must judge your Anki recall honestly.

Keep the rule simple

Again and Hard describe different events: failure versus difficult success. Decide the target before reveal, grade meaning rather than matching every word, and repair cards that make honest grading impossible. Accurate review history gives FSRS better evidence and gives you a clearer picture of what is actually retrievable.
