PSLE prep that finds the gap, fixes it, and feels like play.
Twenty minutes a day. Ottiwise works out exactly which skills your child is missing, picks the next question, and marks their handwritten working the way PSLE does — then helps them fix it themselves.

What a good tutor does, every day, for every child.
One loop, run daily on a map of every PSLE skill. Each turn makes the next one smarter.
Diagnose
Not "weak in fractions" — "takes the second fraction of the whole instead of the remainder". Every wrong answer names the misconception.
Explain
Short films, bar models to drag, science simulations to break on purpose. Toys before tests.
Practise
Endless fresh questions, each one checked by code. Mixed sets train the hardest PSLE skill: knowing which method to use.
Mark & fix
Snap a photo of the working on paper. Method marks in seconds, then a nudge — not the answer — so your child fixes it.
Otti's nudge: How many units did you start with? Count the bar again before you multiply.
Marking that used to need a tutor.
Your child works on paper, just like the exam. One photo, and every step gets PSLE-style method marks. Science answers are checked for each concept point; compositions get one improvement at a time.
Every mark is shown to you, and you can change any of them.
Four subjects. Four different ways to learn them.
Maths
Fluency sprints for the no-calculator paper, then "spot the model": choosing the right heuristic before solving.
Science
Predict, test in a simulation, explain. Open-ended answers rewritten until every concept point is there.
English
Synthesis patterns mastered one by one, evidence-first comprehension, a story studio and oral practice.
Chinese
Daily 字词 review, stories at exactly the right level, and a patient speaking partner for 朗读 and 会话.
Hard practice. Real fun.
The questions stay PSLE-hard. The fun comes from mastery, curiosity and a story: an island map that lights up as skills are learned — and fogs over when they're forgotten, so review is something kids want to do.
- Otti grows with good habits, not raw scores.
- Fixing an old mistake earns more than an easy win.
- Word problems about football, baking or animals — your child picks.
- A clear "done for today". No endless scrolling, no loot boxes.
You stay in charge.
A weekly report in plain words: where each subject stands, the three gaps that matter most and why, and one thing to praise.
No open chatbot
The AI gives hints, marks work and runs oral practice. That's all. In line with MOE's guidance on supervised AI use for upper primary.
Checked by teachers
Questions are original and every answer is verified by code. Teachers review samples and any mark the AI is unsure of.
