A guide to GCSE mock preparation
Your GCSE mocks are one of the most important sets of exams of the year. They not only show you the academic distance from where you are now to where you need to be, but the exams also give you a clear insight into how much work you need to do before the GCSEs in May/June.
If you feel uncertain about when you need to start revising for your mocks or overwhelmed about how much you have to revise, you're not alone. Balancing current schoolwork with revision, or even tackling it when your peers haven't started yet, isn't easy. However, with the right preparation plan, you can do it.
When to start revising for GCSE mocks
Most schools schedule GCSE mock exams in January or February of Year 11, though some schools run additional mocks in November. Check your school calendar as the exact date matters for your planning.
Typical mock exam windows:
1. November mocks: Less common, usually for early assessment or pre-mock exams.
2. January/February mocks: Most common, held after Christmas break
3. Year 10 summer mocks: Early preview, lower stakes
Your revision start date should be determined by working backwards from whichever set you're preparing for.
The ideal mock revision timeline: 8-10 weeks
The 8 - 10 week timing is based on how your brain takes in information and remembers it. German psychologist Hermann Ebbinghaus discovered that we forget information rapidly unless we revisit it. His theory, the forgetting curve, suggests that within 24 hours of learning something, you will have forgotten 70% of it. However, each time you review the material, you will remember it for longer and longer.
This means:
1. Learning something once means it's forgotten quickly
2. Reviewing after 1 day means it's remembered for several days
3. Reviewing after 1 week means it's remembered for weeks
4. Reviewing after 1 month means you will remember long-term
5. 8 to 10 weeks, therefore, gives you time to learn material multiple times with gaps in between for all subjects, which makes this the most effective way to move revision material from short-term to long-term memory.
How to revise successfully for your mocks
Avoid cramming
You may have used last-minute cramming for the odd test with good results, but it doesn't work for GCSE mocks, simply due to the large amount of information you need to take in. Your brain needs repeated exposure over time—spaced repetition—to move information into long-term memory. Cramming creates surface-level familiarity that disappears within days. GCSE mock exams will also test understanding and application, not just memorisation, and cramming doesn't give you time to grasp concepts or practice applying them genuinely.
Start early
Starting your GCSE mock exam revision early also offers significant mental health benefits. By reducing stress and anxiety and focusing on gradual, consistent preparation, you will avoid the overwhelming feeling and panic associated with last-minute revision. Creating a realistic and manageable revision schedule helps you feel organised and in control of the workload, which is a major factor in reducing overall anxiety.
Give yourself time to identify and fix weak areas
Starting early turns revision into a time when you can accurately pinpoint where your knowledge gaps are and fix them. When you start revising, you will quickly discover which concepts feel easy, which ones need more work and which ones you struggle with.
This gives you the space to find out more without the pressure of the real exam in front of you. Struggling is a sign that you need to spend more time focusing on this area or seek extra help from a teacher or tutor.
Understand the purpose of mock exams
Your school will use your mock results to make your predicted grades. However, these exams are also a tool for understanding what you need to do before the real GCSEs take place in May. It's why many students use their mock results as a wake-up call. Significant revision between mocks and the final exams always contributes to further improvement in the final GCSE grade.
10-week mock revision schedule
Weeks 8-10 foundation phase
Goal: 60-minute daily revision plan for 10 GCSE subjects
Strategy: 25 minutes - active revision of two subjects. Followed by 10 10-minute quick review/flashcards for two other subjects.
For example: Monday. 25 minutes revising for Maths. 25 minutes of revision for History. Followed by 5 minutes of flash cards for English Literature and 5 minutes for Science.
Rotate subjects so every subject gets a 25-minute segment and a 5-minute quick review. The foundation stage of revision helps you balance homework and revision time.
Weeks 5-7: knowledge building phase
Goal: To consolidate knowledge, build understanding, and identify knowledge gaps. Increase your revision time to two hours a day and one hour on weekends.
Strategy: Use a mixture of active learning methods
1. Retrieval practice
2. Spaced repetition
3. Practice questions
4. Mind maps
Once you identify a knowledge gap, increase your revision time in this area, and seek active help from teachers and tutors to ensure you understand what's missing from your learning. You're ready to move on when you have a solid foundation in all topics and can attempt questions without constantly checking your notes.
Weeks 4-0: practice phase
Goal: Focus on exam technique and timing errors
Strategy: Use past papers and mark schemes under timed conditions. Put in intensive practice on weak areas.
Score yourself honestly and track results, looking for common mistakes. This means identifying question types you consistently lose marks on. Learn the exact wording examiners want and identify "command words" and what they require from you. Finally, understand how marks are allocated per question type to ensure you get as many marks as you can.
