Lock in. Level up.
JinBoost is a revision companion for PSLE. Your child works through practice papers — on screen or on real paper — and gets them back marked, with the exact step that went wrong explained clearly. Then the oral exam, practised out loud, in five languages.

You found the area of the whole rectangle correctly, then subtracted only one triangle. There are two — subtract 90 cm², not 45.

01 · The main event
A child working through practice papers is only half the job — the other half is knowing what went wrong. JinBoost handles the marking, so feedback arrives the same evening, not next week.
Members of the JinBoost community share the papers they have sat — SA1, SA2 and Prelims across all four subjects. Every paper is contributed and tagged to the MOE syllabus by the community, so there is always something new to practise on.
Timed, on screen, question by question. Submit and it comes back marked in seconds — not next week, when the tuition centre gets round to it.
They work on real paper, the way the exam is actually sat. Photograph it: JinBoost reads the handwriting, marks every sub-part on its own, and awards method marks even when the final answer is wrong.
Not a red cross. The step where it broke, and why — in three depths: the short version, the full reasoning, or a narrated walkthrough drawn out on screen.
Every question is tagged to the MOE syllabus, so a run of wrong answers becomes focused practice on exactly that weakness — revision that follows the mistakes, not the textbook.
A projected AL band per subject, updated after every paper. Based on practice performance — a useful guide, not a guarantee.
02 · The half nobody practises
Your child reads aloud and responds to an AI examiner. JinBoost scores the attempt against the PSLE oral rubric, flags the exact sound or phrasing that needs work, and shows how their own answer could be said better. Available in five languages — including a Tamil oral coach that didn’t exist before.
Oral makes up 15% of the language mark — and it is the component families practise least, because it needs someone to sit and listen. Now it doesn’t.
Try the oral coachThe middle sound was rushed — say it as re-cy-cling, and keep “cy” clear.
You said: “I helped him pick up the books and told the teacher.”
“I think helping him was the right thing to do, because he might have felt embarrassed. For example, I picked up the books first, asked if he was hurt, then told the teacher.”
03 · And when the papers are done
Snap a handwritten composition. Rubric-aligned scores, inline annotations, and a rewritten paragraph showing what a stronger answer looks like.
Text, voice, a sketch, or a photo of any question. Mei explains it step by step, staying within the syllabus.
Timed 1v1 Math and Science duels, weekly leagues. The part that makes them come back the next day.
