Why doing more papers may not improve scores
Some students finish many IGCSE papers but keep making the same mistakes. This usually happens when review is too general: the student checks the mark scheme, writes the correct answer, and moves on.
Four types of past-paper mistakes
Useful review separates mistakes into four groups: concept gaps, exam technique, timing problems, and careless errors. Each group needs a different fix.
A concept gap may require tutoring. A timing issue may require paper strategy. A careless error may require better checking habits.
How to build an error log
An error log should record the paper, question, topic, mistake type, reason for the mistake, and the next practice action. This makes review visible and prevents vague revision.
When to return to core concepts
If the same topic appears repeatedly in the error log, the student should pause broad paper practice and rebuild the core concept. More papers will not fix a foundation that is still unclear.
How past-paper training should work
IGCSE past paper training should include selected questions, timing practice, command-word review, mark-scheme analysis, and targeted follow-up. The aim is better process, not just more completed papers.
When diagnostic support is useful
If the family cannot tell whether mistakes come from topic gaps, exam technique, or timing, an IGCSE Diagnostic Test can create a clearer roadmap before more practice.
