A revision timetable full of subject names still leaves you wondering what to do when you sit down. Replace “revise chemistry” with “a small set of questions, a check against the answers, and a date to redo the mistakes”, and the plan becomes something you can follow.

The idea behind spaced review is simple: the same study time spread over several days is remembered better than the same time crammed into one. Each session is a self-test, not a reread.

Put the exam on the calendar first

Check the official exam date, syllabus and format, then split the material into small topics. Small topics let you come back to each one more than once before the exam. Scheduling a long block of reading and calling it done is the most common mistake.

Let your answers set the next date

No fixed interval works for every subject. Adjust based on how the last attempt went:

  • Couldn’t answer: review the material, then try a smaller question within a day or two.
  • Shaky: test again in a few days.
  • Easy: leave a longer gap, or test it in a new context.

For example: on Monday you try equilibrium questions and get two wrong. On Wednesday you redo those two plus a new one and get them right. The following Monday you do a mixed set.

Missed a day? Don’t double up

After a missed session, use your next free slot for the most important weak topics instead of doubling every later session. Keep time for corrections and rest.

Later on, mixing questions from different chapters helps you practise choosing the right method. You don’t need to shuffle everything from the start.

Try one round with the timer

Forty minutes is one study session, not the gap between reviews:

  • 5 minutes choose material: pick the topics to test from your plan.
  • 20 minutes self-test: notes closed, answer the questions.
  • 10 minutes correct: compare with the answers and write why each mistake happened.
  • 5 minutes schedule: put the next attempt for each weak topic on your calendar.

A checklist won’t schedule the dates for you, so use the last five minutes to write them in.

Next

Pick the checklist for your exam: exam preparation, final exam revision or language test preparation. Add your exam date when you copy it to see how many days are left. For how to run each self-test, see active recall.
