Guides, techniques, free resources and structured courses. Plan your revision, practise with exam questions and track your progress to exam day.
GCSE revision can feel overwhelming — so many subjects, topics and techniques. GCSEs are graded on a numbered scale (1–9), and doing well in your GCSE exam in core GCSE subjects supports your next steps whether you stay at school or college or move on to A-Level courses and higher education. This hub brings it together: how to revise effectively, where to find free GCSE revision resources, and how a structured online course can give you feedback and focus. Whether you're looking for revision techniques, subject-specific guides (like GCSE Maths or Science), or a list of the best free GCSE revision websites, you'll find links below. StudyVector offers both free resources and a full GCSE revision course experience so you can start with no commitment and upgrade when you want more structure and feedback.
GCSEs (General Certificate of Secondary Education) are qualifications taken by most students in England, Wales and Northern Ireland at the end of Year 11, usually at age 16. GCSEs are graded on a scale from 9 to 1 (9 being the highest), replacing the old A*–G system. Your GCSE results affect which subjects you can take at A-Level, which level courses you can access at sixth form or college, and often the entry requirements for apprenticeships and jobs. Doing well in your GCSE exam in core subjects — especially Maths, English and Science — keeps your options open for higher education and beyond.
That’s why GCSE revision matters. Effective revision doesn’t mean re-reading the same notes for hours. Research shows that active recall (testing yourself), spaced repetition (revisiting topics at intervals) and practice questions lead to much better retention than passive reading. A good GCSE revision plan mixes these techniques and focuses on your weak areas. This hub points you to free resources, proven revision techniques and structured courses so you can build a plan that works for you.
There’s no single right answer — it depends on how many GCSE subjects you’re taking and how confident you feel. Many students do light revision in Year 10 (going over topics as they’re covered in class) and step up to a more structured timetable in Year 11. A common approach is to start focused revision 3–6 months before your first exam, so you have time to cover all subjects without cramming.
If you’re at school or college, your teachers will often set mock exams and revision milestones; use those to decide when to intensify. Starting earlier with shorter, regular sessions is usually better than leaving everything to the last few weeks. StudyVector’s revision planner lets you enter your exam dates and target grades, then suggests a day-by-day plan so you can spread the workload and still have time for rest.
The best GCSE revision resources match your exam board (AQA, Edexcel, OCR, Cambridge IGCSE, etc.), cover the full syllabus and give you practice with exam-style questions. Free resources — including our free GCSE revision websites round-up and StudyVector’s own free plan — are a good way to start. You get access to topics, explanations and some practice without paying.
If you want more structure, a GCSE revision course can act like an Easter revision or crash course: a clear sequence of topics, regular practice and feedback so you know what to do next. Look for courses that adapt to your level, show your weak areas and align with the graded scale and command words used in real GCSE exams. StudyVector’s courses do exactly that for Maths, English and Science, with the option to try free first and upgrade when you’re ready.

Sample topic depth
Percentage change appears everywhere in GCSE Maths — from shop discounts to interest and data questions. Examiners reward clear structure: find the change, divide by the original, then multiply by 100. Reverse percentages are the same idea backwards: treat the new amount as a percentage of the original you do not yet know.

Example 1
Basic increase
A £40 jacket increases in price by 15%. Change = 0.15 × £40 = £6. New price = £40 + £6 = £46. As one multiplier: £40 × 1.15 = £46.
Example 2
Reverse percentage (after a sale)
After a 20% reduction, a console costs £360. What was the original price? Sale price is 80% of original → 0.8 × original = £360. Original = £360 ÷ 0.8 = £450. Check: 20% off £450 is £90, leaving £360.

1. A stock rises from £50 to £58. What is the percentage increase?
Correct: 16%Change = £8. 8/50 = 0.16 → 16%.
2. A population falls by 30% to 14,000. What was the population before the fall?
Correct: 20,000New = 70% of old → old = 14,000 ÷ 0.7 = 20,000.
3. Which step is always wrong for percentage change?
Correct: Dividing the change by the new valuePercentage change uses the original value as the denominator.
