Singapore families often spend hundreds per month on tuition. A well-maintained mistake book helps you get more value from every dollar — by turning repeated errors into targeted improvement.
Why a mistake book matters for PSLE
PSLE Math tests problem-solving under time pressure. Students who only redo assessment books without reviewing past mistakes often repeat the same errors in exams. A mistake book tracks:
- Which topics cause the most errors (e.g. fractions, area, age problems)
- Whether errors are careless or conceptual
- Progress over weeks and months
The 4-step review loop
- Capture — Photo or copy wrong questions from homework and past papers.
- Analyse — Identify the root cause, not just the correct answer.
- Archive — Tag by topic (aligned with MOE syllabus).
- Practice — Do similar questions until the concept sticks.
Manual vs AI mistake books
Traditional cut-and-paste notebooks work, but busy parents struggle to keep up. ZY Math uses AI to grade homework, save mistakes automatically, analyse weak areas, and generate practice sets — supporting both English and Chinese math questions common in Singapore schools.
