I run PSLE Hero — a free Singapore PSLE practice platform with worked answers, built for families preparing for the Primary School Leaving Examination.
What we publish and host, openly:
- PSLE Hero (pslehero.org) — PSLE practice across Maths, English, Science and Chinese, with step-by-step worked answers. 5,500+ adapted questions from real Singapore primary-school preliminary exams, free for everyone.
- Singapore Primary Mathematics Syllabus 2021 Dataset (P1–P6) — open, page-verified compilation of MOE's 2021 syllabus in CSV + JSON, CC BY-NC 4.0. DOI: 10.5281/zenodo.24053661
- AI-authored exam guides with full provenance — every factual claim traceable to the official MOE document or SEAB; every row manually verified against the source PDF.
Principles, plainly:
- Free, open resources over paywalled exam prep — exams are not a secret.
- Verified beats verified-by-another-model: every dataset row checked against the official PDF, symbol by symbol.
- AI tutoring is useful only when the answers are honest — show the working, cite the source.
