How many hours a day should I revise for GCSEs?

In term time, one to two focused hours on school days is realistic for most students, more at weekends and in the holidays. Focus and method matter more than total hours.

Is it too late to improve after mocks?

No. Mocks are designed to show where marks are being lost, and many students improve by one or two grades between mocks and the summer with targeted practice.

Are IGCSEs harder than GCSEs?

They cover similar content but differ in structure, coursework and assessment. Check your board's specification and past papers rather than relying on general comparisons.

GCSE Revision Plan: A Month-by-Month Guide

A GCSE revision plan that works

By the Top Tutors Online editorial team · Updated 4 November 2026 · 3 min read

The short answer

Good GCSE revision starts in the autumn of Year 11, not after Easter. Map every subject against its specification, use active methods such as retrieval practice and spaced repetition, use mock results to find weak topics, and move to timed past papers from the spring. Little and often beats long, last-minute sessions.

Key points

Start in the autumn of Year 11 with a list of topics for every subject.
Use active revision: testing yourself works better than re-reading.
Use mock exams to find weak topics, then fix them first.
From spring, practise full past papers under timed conditions.
Check your exam board, because papers and specifications differ.

Know your exam boards

GCSEs in England are graded 9 to 1, with 9 the highest. Each subject follows a specification from a board such as AQA, Edexcel (Pearson), OCR or WJEC Eduqas. Ask teachers which board and tier you are sitting, download the specification and past papers from the board's website, and use them as your checklist.

Month by month

September to October: list every topic in every subject and rate your confidence red, amber or green. Set up flashcards for facts, formulae and quotations.
November to January: revise for mocks. Afterwards, go through every paper and note which marks were lost and why.
February to March: work through red and amber topics. Start mixed practice questions in maths and the sciences.
April: full past papers under timed conditions, marked against the mark scheme. Focus on exam technique.
May to June: short, targeted sessions on the subjects coming up next, with plenty of sleep.

Techniques that work

Retrieval practice: close the book and write or say what you remember, then check. Flashcards and practice questions do this well.
Spaced repetition: return to a topic after a day, a week and a month, rather than revising it once for hours.
Interleaving: mix question types, especially in maths and science, so you learn to recognise which method to use.
Mark scheme study: learn exactly what examiners reward, particularly in English, history and the sciences' extended answers.

Using past papers well

A past paper is only useful if you mark it honestly and act on what it shows. Keep a log of mistakes by topic, redo the questions you got wrong a week later, and read examiner reports, which explain common errors each year.

When a tutor helps most

Tutoring adds the most value after mocks, when you know which topics are weak but are not sure how to fix them, and in subjects where technique decides the grade, such as English and Maths. A GCSE tutor can turn a list of weak topics into a clear plan.
