Work out a realistic weekly revision plan. Enter your level, number of subjects, time until exams and target intensity to get suggested hours per subject and in total.

Indicative, not a rule. Commonly recommended totals in the final run-up sit around 15 to 20 hours a week; adjust for coursework, energy and how far you are from your target grades. One full rest day a week is part of the plan.
This is a rule-of-thumb model, not research-grade science. The baselines mirror what UK study-skills sources (Seneca Learning, Save My Exams, Immerse Education) commonly recommend: roughly 1.5 hours per subject per week at GCSE during term time, 4 to 6 hours per subject per week at A-level, scaling up as exams approach.
Your target intensity and time remaining apply multipliers on those baselines. The output is deliberately a suggestion to adapt, revision quality (active recall, past papers, marking against the scheme) matters more than the raw hour count.
If a subject is stubbornly behind, a specialist tutor can pinpoint the weak topics and focus your revision hours where they move the grade. TutorLab tutors set their own rates and you contact them directly, one all-in price, see what tutoring costs in 2026.
A commonly recommended baseline is around 1.5 hours per subject per week during term time, so 12 to 15 hours a week across 8 to 10 subjects, rising to 15 to 20 hours a week in the final run-up to exams. Quality matters more than quantity: active recall and past papers beat re-reading notes.
Study-skills sources commonly suggest 4 to 6 hours per subject per week at A-level. With three subjects that is 12 to 18 hours a week, scaling towards the top of that range in the final term before exams.
Yes. Beyond roughly 20 to 25 hours a week most students hit diminishing returns, retention drops and burnout risk rises. This calculator caps its suggestion at 30 hours a week and recommends one full rest day. Shorter, focused sessions with breaks outperform marathon days.
Earlier and lighter beats later and heavier. Starting 3 or more months out at a steady pace lets you cover every subject twice and leaves the final weeks for past papers and weak-topic repair, rather than first-pass learning.
No. This calculator gives an even split as a starting point, but you should weight hours towards your weakest subjects and the ones with the biggest gap to your target grade. A tutor can help identify exactly which topics are costing you marks.
