A revision timetable you’ll actually keep

Most timetables fail in the first week because they’re too ambitious. Realistic plans beat perfect ones.

Key takeaways

1. Start from the exams

Write your exam dates on a calendar first. Count the weeks you have, list every topic for each subject, and spread the topics across the weeks so that each one comes round at least two or three times before the exam.

2. Plan for the planning fallacy

Psychologists call our habit of underestimating how long tasks take “the planning fallacy”. In one study, students predicted how long their final-year thesis would take. On average, they took longer than even their own worst-case estimates.[2]

So plan for about 80% of the time you think you have. The spare slots catch up on what slips.

A timetable you follow at 80% beats a perfect one you abandon on Wednesday.

3. Use if-then plans

“I’ll revise more” rarely works. “If it’s Tuesday at 5pm, then I do 30 minutes of maths at the kitchen table” works much better. Research on these “implementation intentions” finds that linking a specific action to a specific time and place makes people far more likely to follow through.[1]

4. A weekly template

Slot
Example
Weekday after school
2 × 30-minute blocks, different subjects
One evening
Review: quick tests on last week’s topics
Weekend
One timed past-paper question per subject
Every Sunday
10 minutes to review and adjust the plan

For parents: Help your child plan the week on Sunday. Agreeing the plan together works better than checking up on it every evening.
