For parents · Singapore O-levels
Help your child prepare for the O-levels. PrepLab finds exactly where they’re weak.
PrepLab gives Sec 3–4 students 15-minute daily practice built around O-level exam questions across A-Math, E-Math, Physics, Chemistry and Biology. Every session logs mistakes. Every mistake sharpens what comes next — and your linked parent account shows you exactly where they’re weak, before results day.
A loop that gets sharper the more they use it
Pick a topic, start a set
15-minute practice sets built around O-level exam question formats. Sec 3–4 content across all five subjects. Short enough to do after dinner.
Mistakes become the next session
PrepLab surfaces exactly which question types trip them up most — not just “you got this wrong”, but which topics keep appearing in their mistake list.
Results day is not a surprise
Students who know what they’re weak in — and have practised those topics repeatedly — walk into the exam prepared.
What parents ask before sharing
Is this a replacement for tuition?
No — and it’s not trying to be. PrepLab is the daily practice habit that makes tuition more effective. Think of it as consistent targeted reps between sessions.
Is the content aligned to the MOE O-level syllabus?
Yes. Every question is built around the Singapore O-level syllabus for Sec 3 and Sec 4 students, across A-Math, E-Math, Biology, Chemistry, and Physics.
Is it free?
Yes, PrepLab is free to use. Your child signs up and starts practising immediately with no payment required.
How can I help my child prepare for the O levels?
The biggest lever is consistent, targeted practice — not more hours. PrepLab gives your child a 15-minute daily session focused on their actual weak topics, and gives you a linked parent view so you can support them without hovering.
Will my child actually keep using it?
That’s the right question. PrepLab is built around a daily streak and a mistakes-to-revisit loop — so there’s always a clear reason to come back. Early pilot students moved from needing reminders to opening the app on their own.
Do I need to set it up for them?
No. Students sign up and start practising independently. You can link a parent account using a short code your child generates — it takes under a minute.
