IGCSE Maths Mock Exams: How to Make the Most of Your Results

What the Mock Exam Actually Tells You

School mock exams for IGCSE maths are typically held in October or November of Year 11 (for May/June candidates). For most students, the mock result is the most accurate predictor of their real Cambridge grade — and the most useful diagnostic tool available.

The mock result is not just a grade to be proud of or disappointed by. It is data. Used correctly, it produces a targeted revision plan that is far more efficient than generic preparation.

Step 1: Get the Paper Back

Not all schools return marked mock papers to students. If your child’s school doesn’t return papers, ask the teacher:

• Which topics did my child lose the most marks on?
• Was the lost marks pattern more from short-answer (Paper 2 equivalent) or long-answer (Paper 4 equivalent) questions?
• Were there common patterns in where marks were dropped?

If the school does return papers, sit down with the Cambridge mark scheme (available from the Cambridge website) and work through it question by question.

Step 2: Classify Every Mark Lost

For each question where marks were dropped, categorise the loss:

• Type A: Didn’t know the topic at all (concept gap)
• Type B: Knew the topic but made an arithmetic or reading error (careless)
• Type C: Got the answer right but lost marks for missing working or missing reasons (presentation)
• Type D: Ran out of time and didn’t attempt (time management)

A typical Year 11 student at B/C level loses roughly:

• 20–30% of dropped marks from Type A (topic gaps)
• 30–40% from Type B (careless errors)
• 20–25% from Type C (presentation)
• 10–20% from Type D (timing)

Step 3: Build the Priority List

Rank the topics where Type A losses are highest. These are the first tuition priorities.

Address Type C losses immediately — they require habit change, not new knowledge, and are fast to fix.

Address Type D losses through timed paper practice — Paper 4 in particular must be practised end-to-end under strict 2h30m timing.

Step 4: Set a Revised Target

A student with a D+ mock result (5–6 months before the real exam) is typically on track for a C with well-targeted preparation. A B mock result with 4 months to go can become an A with focused effort. Use the table from our grade boundary guide to translate your child’s mock raw marks to a grade projection.

How Teacher Rig Uses Mock Results

When a new student joins after their mock, Teacher Rig requests the paper or the teacher’s topic feedback and uses it to build the first revision plan directly from the diagnostic. No time is wasted on topics your child already understands.
