Exam practice that marks itself — and tells you why
Bilingual practice for Chinese, English, Math, Science and Humanities, from single characters up to full compositions. Work is marked the moment it is submitted, with a written critique and an improved version to compare against.
43 of the 46 exercises are open on the free plan, with a fresh daily allowance every day. I already have an account

The problem
Practice stalls for the same five reasons
None of them are about effort.
Marking arrives too late
A composition handed in on Monday comes back on Friday. By then the student has moved on, and the correction lands on nothing.
A score with no reason
A mark out of 20 says how it went. It does not say which paragraph lost the marks, or what a better version would have read like.
Material runs out
Past papers get used up, and worksheets rarely cover oral, dictation and comprehension in the same place.
Oral practice needs another person
Speaking is the hardest paper to rehearse alone, so most students quietly skip it until the week before.
Mistakes never come back
A wrong answer is corrected once and never asked again, so the same gap turns up in the exam.
The platform
One study surface for every paper
46 exercises, one account, and one place where the marks and critiques accumulate — built on a 56,000-word curriculum with grammar-broken-down example sentences.
Marked on submit
Objective questions are checked instantly; open-ended work goes straight to an AI examiner instead of into a marking queue.
Every subject in one account
Chinese, English, Math, Science and Humanities sit side by side, so revision is one routine rather than five apps.
Bilingual by default
Every screen switches between English and 中文, so a student and a parent can each read it in their own language.
What you can practise
One routine, every subject
Short, self-marking exercises grouped the way a syllabus is — vocabulary, reading, writing, speaking, and full exam papers.

Free plan
Sign up free, practise today
A free account is the normal way to use the site, not a trial that expires. It costs nothing, needs no card, and takes about a minute.
43 exercises unlocked
Characters, idioms, reading, dictation, composition, oral, math and science are all open on the free plan.
A daily allowance that resets
Free accounts get a set number of units per exercise each day. Come back tomorrow and the allowance is back.
AI marking included
Free work is marked the same way paid work is — a mark, a written critique, and an improved version to compare against.
Nothing to install, nothing to cancel
It runs in the browser, including the microphone recording used by the oral and read-aloud exercises.
Paid plans only raise the daily allowance and add the AI conversation exercises. Everything else is in the free plan.
How it works
Practise, get marked, fix the gap
- 1
Pick an exercise
Every exercise opens on the next unit you have not done yet, so there is nothing to set up and nothing to plan.
- 2
Answer it and get marked
Objective questions are checked the moment you submit. Compositions, oral recordings and math working go to an AI examiner that returns a mark, the reasoning behind it, and an improved version.
- 3
Review what you missed
Every wrong answer collects in one revision list, and a teacher can assign the next set of units for you.
Who it is for
Four kinds of user, one account each
Primary students
PSLE Chinese, English, Math and Science — full paper-style sets plus the composition, oral and comprehension components on their own.
Secondary students
Secondary Chinese and English papers, E Math, Science and history essays, marked against the same criteria as the real thing.
Parents
See what was practised, what it scored and what the examiner said — in English or 中文, without having to mark anything yourself.
Teachers and tutors
A dashboard of every student attempt, the ability to re-mark any piece of work, and practice packages assigned unit by unit.
Why students stay
Built around the Singapore papers
Exam-aligned
PSLE and secondary papers for Chinese, English, Math and Science, in the same format and mark scheme as the real thing.
Marked in writing, not just scored
Each AI-marked answer comes back with the mark, the reasoning behind it, and a rewritten model answer to compare against.
Speaking and listening included
Record oral answers and read passages aloud. Pronunciation, tone and fluency are scored from your own recording.
Bilingual throughout
The whole site switches between English and 中文, so a student and a parent can each read it in their own language.
Teacher dashboard
Teachers see every attempt, re-mark any piece of work, and assign practice packages unit by unit.
Progress you can see
Past attempts, marks and critiques are kept per exercise, so improvement over a term is visible rather than guessed at.
Common questions
Is it really free?+
Yes. A free account opens 43 of the 46 exercises with a daily unit allowance that resets each day, and free work is marked by the same AI examiner as paid work. No card is needed to sign up.
Who is it for?+
Primary and secondary students in Singapore preparing for PSLE and O-Level papers, and anyone learning Mandarin from single characters up to full compositions.
How is written work marked?+
Objective answers are checked by exact comparison first. Anything open-ended — compositions, oral responses, math working — goes to an AI examiner that returns a mark, a critique and an improved version.
Do I need to install anything?+
No. It runs in a browser, including the microphone recording used by the oral and read-aloud exercises.
Can teachers use it with a class?+
Yes. Teachers get a dashboard of their students' attempts, can re-mark any piece of work, and can assign practice packages per exercise.
What do the paid plans add?+
A higher daily allowance and the AI conversation exercises. The exercises themselves are the same ones a free account sees.
