A Spaced Repetition Schedule When the Exam Is Three Weeks Away
Most spaced repetition schedules for exams are built for a year of retention, and yours has three weeks. With a dated paper that close you do not need long intervals. You need three or four retrieval attempts on each topic, all of them landing before the date, placed backward from the exam rather than forward from today. What comes back in each session should be chosen by the questions you got wrong in the last one.
What spacing can and cannot buy you in three weeks
Spaced repetition works because a memory you nearly lost and then recovered comes back stronger than one you reread while it was still fresh. The effect does not need months. It needs a gap long enough that recall is a little effortful, and for material you met last week a day is usually long enough.
Three weeks cannot buy you the year later retention the spacing research describes, because that kind of durability is built from reviews spread across the whole year. You get three or four attempts per topic, and their value is discovery more than durability: each attempt tells you what is missing while there is still time to fix it. A topic still new to you with five days left is a topic you are cramming, which is a fair trade for something you need once on a known date.
Why a long interval scheduler sends cards past the exam date
A scheduler like Anki is built for an open ended horizon. Answer a card well and its next interval multiplies: days become weeks, weeks become a month or more. Rate a card Good with twenty days to go and a twenty five day interval drops its next review five days after the paper. Nothing warns you. Your deck looks finished and the topic has left your schedule.
None of that is an argument against the program. The comparison page here grants what Anki does better: a scheduler refined for two decades, free and open source clients with offline study, large shared decks for standardized exams, and complete control over card wording. Keep the deck. For three weeks, force the intervals down with custom study or a filtered deck that ignores due dates, and stop letting the due count decide what your day contains.
Counting backward from the date: sessions, not days
Write the exam date at the top of a calendar, then stop counting days, because days are not the unit you spend. Count sessions instead: blocks of forty five to ninety minutes in which you answer questions rather than sit near your notes. Two sessions on a good day and one on a bad day comes to about thirty across three weeks, and it is worth planning for fewer than you expect to get.
Then place the attempts backward from the date. A topic whose first pass falls on day 18 wants retrieval at roughly day 17, day 14 and day 7, plus a short contact inside the last three days. The gaps grow and all of them close before the paper, which is the whole point of scheduling backward. A topic first met on day 6 gets the same shape compressed: day 5, day 3, day 1. Number the days down to zero and a review cannot quietly land after the exam.
Retrieval attempts, not re-reads: what counts as one repetition
A repetition counts when you produced an answer before you saw one. Nothing else counts. Rereading a highlighted chapter and copying notes into a neater document both leave the same false fluency, because recognizing material is much easier than retrieving it. Every slot on your plan holds questions, not pages.
Making the questions is where most plans die, since writing twenty good ones from a lecture takes longer than reading the lecture did. That is the gap this site closes: upload the deck or the chapter and the questions come back written from its own sentences, each printed with the quote it was built from and the page or slide that line sits on. Those checks are set out on how it works, and the practical notes on getting usable items out of a deck are on turning lecture notes into exam questions. One measured timing, taken on September 23, 2026 on the free pool: 20 questions from a 44 to 60 page textbook chapter in about 15 to 18 seconds.
Letting the questions you missed pick the next session
A spaced repetition schedule for exams usually decides the order for you. With a fixed date, that is the wrong authority. The best signal for what to study next is not an algorithm's estimate of your memory strength. It is the list of items you got wrong yesterday, because those are the places where you have evidence rather than a self-rating.
So let each session produce the next one. Grade the set, keep what you failed, and put those items at the front of the following slot for that topic. Two thirds failed items and one third fresh questions from the same chapter is a workable split, since an item you have seen three times starts testing your memory of the question instead of the fact behind it.
This site runs that loop if you let it. Missed questions go into a review queue that is served first, later exams are weighted toward your weak topics, and a graded paper returns an A to F grade with mastery broken down by chapter, so the weakest chapter claims the next slot. The page for medical students describes the same loop from the student's side.
A worked three week plan for one module
Copy this and change the nouns. The module is cardiovascular physiology, four lectures plus one assigned chapter, and the paper is twenty one days away on a Friday morning.
- Days 21 to 18, first pass. One lecture per session: read it once, generate twenty questions from it, answer them cold. Your list of failures is the map.
- Day 17. Lectures 1 and 2: everything you missed, then twenty fresh questions from the same two lectures.
- Day 16. The same for lectures 3 and 4, with a first pass over the assigned chapter in the second session.
- Days 14 and 13. Second attempt on lectures 1 to 4, one pair per session, misses first. Switch the question type: single best answer becomes clinical vignettes, so the same facts are tested as reasoning.
- Day 11. Chapter retrieval plus a mixed set drawn from all five sources, the first session where you do not know a question's topic in advance.
- Days 9 and 8. Third attempt on the two chapters with the worst mastery. The rest get nothing this week, on purpose.
- Day 6. A 100 question mixed paper in one sitting, on a clock. Read the debrief, not just the score.
- Days 5 to 3. Misses from that paper, grouped by chapter, one chapter per session. Add short answer items for anything you may have to explain out loud.
- Day 2. A second full timed paper from the same five sources, a fresh draw.
- Day 1. Two short sessions on items you have now failed twice. No new material. Sleep.
Two properties matter more than the details: every topic is retrieved at least three times with growing gaps, and every gap closes before the date. If your version leaves a topic whose last contact is day 12, move something.
A plan this size runs past the 300 verified questions a month a free account gets, which is what the 90 day Exam Pass at $19.99 and the 500 question pack at $5.99 are there for. Generating one chapter at a time, and stopping once the new questions stop surprising you, keeps the count down.
When to stop drilling questions and take full timed papers
Question sets teach you facts. They do not teach you the exam. Around six days out the value shifts from drilling more items to sitting whole papers under the real time limit. Three things show up only there: pacing, the fatigue that arrives in the last stretch of a long paper, and interleaving, since a real paper never tells you which chapter a question came from.
Build the paper from several chapters at once, sit it in one go with no pauses, and spend a whole session on the result. Stop adding new material about two days out, because a topic met on day one gets no retrieval attempt at all. The sample exam is ten questions with no upload and no account if you want to see the format first.
Keeping what you learned after the exam is over
The day after the paper the schedule inverts. Long intervals stop being the problem and become the point, because this material comes back in a final, on a rotation or in a licensing exam. Carry forward the facts you failed twice in the last three weeks, not the whole bank.
Paid plans here download an exam or a whole document as tab separated Anki text, as a CSV or as a printable page, and each question takes its answer, its quote and its page number with it, so that short list never has to be retyped. Hand it to a scheduler and let it do what it is good at. That is the split the comparison page recommends: practice exams tell you what you do not know, and spaced cards keep what you learned from leaking away before finals. Pricing puts the free monthly allowance next to the one time options.
Questions people ask
What does a spaced repetition schedule for exams look like week by week?
Week one is a first pass on each topic with a retrieval attempt the next day. Week two is a second attempt on every topic at a three to five day gap, misses first, with the question type switched. Week three is full timed papers built from several chapters, then the items you have failed twice, and no new material inside the last two days.
Is spaced repetition worth it with only two weeks left?
Yes, with lowered expectations. Two weeks gives most topics two or three attempts instead of four, so space them about one day, three days and six days apart and aim them at whatever your last graded set showed you failing.
Is spaced repetition better than cramming before a medical school exam?
On a three week horizon they are two ends of one schedule rather than alternatives. Topics you met early get spaced retrieval; topics you meet in the last week get compressed attempts that look like cramming. The mistake is cramming a topic you had three weeks to space.
How many times should I answer a question before the exam?
Twice is usually enough if you got it right both times and the second attempt came a few days after the first. Anything failed twice earns a third and a fourth. Past that you start remembering the question, so swap it for a different one about the same fact.
How do I get practice questions for a module with no question bank?
Generate them from the material you are examined on. Uploading the lecture deck or the assigned chapter returns questions written from its own sentences, with the quote and the page number attached, which is what makes each one checkable.
