Your exam is in a week. How to spend the seven days so it sticks

The seven days, in short

1. Tonight, list the topics. Put the ones most likely to be tested at the top. If there are too many, cut from the bottom.
2. Learn each topic once, then test it. End every session by closing the book and writing what you can recall. Then check and fix the gaps.
3. Come back after 1 to 3 days. Each topic gets at least two more closed-book reviews before the exam.
4. Use the evening for the hardest topic. Recall it for ten minutes the next morning, before anything else.
5. Keep your normal bedtime every night. That is your study cutoff, all week.
6. In the last two days, review everything once or twice. Keep these sessions short, a day apart.

This is our sketch built from the tools in the book, not a tested schedule. The pieces each have research behind them, and the next sections show it.

Why the cram night feels better than it works

Picture a parent at ten on a Thursday night, quizzing a teenager on a history test that is tomorrow. By eleven-thirty he knows every date. He gets a decent grade. Three weeks later the same material shows up on a cumulative quiz, and he can barely start an answer.

That is cramming doing exactly what it is built to do. It works for one day.

Spacing the same hours out works for longer. In a 2008 study by Cepeda and colleagues, more than 1,350 people learned facts, reviewed them after a gap, then took a final test. For a test one week away, the best gap was about 20 to 40 percent of that week. That is roughly 1 to 3 days. Being a little off the best gap cost little. Having no gap at all is what costs you.

Cramming also fools the person doing it. In a 2009 flashcard study by Kornell, spreading the practice out beat massing it. Yet 72 percent of learners believed after the first session that massing had worked better. So expect your spaced week to feel less sure than a cram night. That feeling is not a verdict.

What you do in each session matters as much as when. Make every review a test, not a reread. On tests 2 days and a week later, students who practiced recall beat students who restudied, in a 2006 study by Roediger and Karpicke. With a week left, that is the trade to make.

Sleep is part of this week's plan

When time is short, sleep looks like the one thing you can cut. The research says it is doing part of the studying.

In a 2016 study by Mazza and colleagues, 40 people learned foreign words in two sessions, 12 hours apart. One group studied in the morning and again that evening. The other studied in the evening, slept, and studied again the next morning. The sleep group needed about half as much practice to relearn the words in the second session. They also remembered more at one week and six months.

That is why the plan puts the hardest topic in the evening and a short recall the next morning.

Now the other side. Meta-analyses by Newbury and colleagues in 2021 found that losing sleep after learning hurt memory by a small amount. Losing it before learning hurt more. The authors also found signs of publication bias, so the exact sizes are loose. The direction is the same in both.

One more study is useful in exam week. Okano and colleagues gave activity trackers to 100 chemistry students, and 88 finished. Sleep on the night before a test showed no link to the score. Sleep across the week and month before did. We read that as a plain message: the whole week counts, not only the last night.

This describes research only. If you have ongoing trouble sleeping, talk to a health care provider.

Where the book picks up

Stop Rereading was written for adults studying for an exam on top of a full life. Each of its 30 tools carries a badge for its evidence. With a week left, three chapters matter most.

Retrieval Practice: Pull It Out, Don't Pour It In has the Blank Page and Flashcards Done Right, both SOLID. The Blank Page is ten minutes with a closed book, then a second pen for the gaps.

Spacing: Less Cramming, More Coming Back has the Spacing Calendar (SOLID). Its last step fits this week: in the final days, add one or two short reviews of everything, a day or two apart.

Sleep Is Part of Studying has Study, Then Sleep and the No All-Nighter Rule, both SOLID. If you fall behind, move work earlier or cut scope. Do not move it later.

If the exam is further off than a week, our page on how far apart to space study sessions has the gaps for longer waits.
