Enter your topics and when you last revised each one. This tool will find the ones that are overdue — before your exam finds them for you.
⏱ Takes about 3 minutes
For each topic, the tool calculates how many days have passed since your last revision. It then compares that against the safe interval you selected. Any topic past that interval is flagged as a gap.
Topics closest to your exam date with the biggest gaps are highlighted first — so you always know what to tackle first.
Memory fades faster than most students expect. Research shows that without revision, we forget up to 80% of new information within a week. The longer the gap, the harder it is to recall — and the more time it takes to re-learn.
Regular spaced revision — even just 15 minutes per topic — keeps material fresh and makes exam preparation dramatically easier.
For most subjects, revisiting a topic every 5–7 days is a reasonable pace. In the final week before an exam, you might want to reduce that to every 2–3 days for the most important topics.
Any active engagement counts — answering practice questions, writing a summary from memory, teaching the topic to yourself, or making a quick mind map. Just reading passively does not count as effective revision.
Not necessarily. Topics with bigger gaps, bigger mark weightings, or where you're weakest should get more attention. Use the gap finder alongside your syllabus to prioritise.
Yes — use the Save button after generating results. Your topic list is saved in your browser's local storage so you can come back without re-entering everything.
You can add as many topics as you need. There's no limit. For very long lists, you might want to group by subject first to keep things readable.
