About AceLah
AceLah is a Chinese-language practice platform for Singapore primary school pupils, Primary 1 to 6. It brings four things together: an original question bank aligned to the MOE syllabus and organised by knowledge point (about 9,600 questions, marked automatically, with mistakes retested on day 3, 7 and 21); dictation cards for every textbook lesson; PSLE mock papers built to the real paper structure; and revision guides written from frequency analysis of 266 top-school prelim papers. Children earn shells by practising and raise a buddy; parents get a weekly report they can actually read. AceLah is an independent product, not affiliated with Singapore's MOE or SEAB.

Where the questions and data come from
Every question is original, written to the character lists and knowledge points of the MOE Huanle Huoban textbooks, checked by a separate reviewing pass and blind-answered by three models to verify the keys. Nothing is scraped from online papers and no exam text is reproduced. The frequency data comes from 266 deduplicated top-school P6 prelim papers, 2021 to 2025, and records only which words were tested and how often.
Who makes it
AceLah is built by a Chinese teacher with years of classroom experience in Singapore and a parent, starting from their own children's primary-school Chinese: free papers are everywhere, but nobody marks them, tracks them, or turns the mistakes into retests. Ideas and bug reports: hello@acelah.com.
