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 7,000 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 five years of exam-point frequency analysis. 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.

What AceLah does, one fact per line
- Automatic marking: every answer is marked on the spot, with an explanation in Chinese.
- Mistakes queue themselves: a missed knowledge point is retested with a different question on day 3, 7 and 21, and counts as mastered only after repeated correct answers. No mistake book to copy out.
- Two sets a day: after logging in there is one button; each set has 5 to 15 questions (by grade) chosen by the child's mastery and takes about ten-odd minutes.
- Aligned to the MOE syllabus: questions are organised by the knowledge points and question types of the Huanle Huoban textbooks, Primary 1 to 6, standard Chinese.
- Dictation that follows the textbook: character cards for every lesson; pick the grade and lesson and it is the words the school tests this week, online or printable.
- PSLE mock papers: five original full mock papers (Paper 1 + Paper 2) built to the real PSLE structure; multiple choice marked on submission.
- Frequency data: five years (2021 to 2025) of P6 high-frequency words and knowledge points, written up as revision guides.
- Children come back on their own: practice earns shells to raise a buddy, grow fruit trees, buy decor and send postcards; streaks that drop to the last milestone instead of zero.
- Weekly report: which knowledge points were mastered this week and which tier each of the five skills sits at; Premium adds a grade readiness score and the three points most worth working on.
- Nothing to install: runs in the browser on phone, tablet or computer, and can be added to the home screen.
- Price: the free plan covers two sets a day, dictation and the first 2 full mock papers; Premium is $9.90 a month, currently free for a limited time, unlocked with a code during the free period, no card required.
- What it does not do: no automatic marking of oral or composition yet; not a tuition centre; not affiliated with 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 answered independently in several rounds to verify the keys. No exam text is reproduced. The frequency data 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.
