    Questions parents ask

    FAQ

    Where do the questions come from?

    P5 booklets use 2025 P5 End-of-Year exams and Weighted Assessments; P6 booklets use 2026 P6 Preliminary exams, all from Singapore primary schools. Each question is retyped and labelled with its source. We are an independent resource and are not affiliated with MOE or any school.

    Are the answers reliable?

    Every answer is typed and checked against the school's own answer key. Where a school did not publish an answer, we work it out, and the key explains how.

    Is it the current syllabus?

    Yes. The questions come from 2025 and 2026 papers, set on the current MOE Primary Science syllabus.

    Can I print it more than once?

    Yes. Print as many copies as your own children need. Each PDF is licensed to one family and carries the buyer's name, so please don't share it outside your household.

    How do I pay?

    By PayNow. After you send your order request, we WhatsApp you within a day with the total, your order reference and our PayNow details. You don't pay anything on this website.

    How soon will I get the PDFs?

    Usually within a few hours of your PayNow payment, between 9am and 10pm. Payments made late at night are delivered the next morning.

    What do you do with my email and phone number?

    We use them only to confirm your order, send your PDFs, and tell you when a topic you asked about is ready. We never share them.

    Which topics are available?

    P5 Science: Reproduction in Animals, Reproduction in Plants, Heat Energy, Water Cycle, Transport System in Plants, Body Systems and Electricity. P6 Science: Energy, Forces, Food Chains and Food Webs, and Interactions within the Environment. The P6 booklets use 2026 Prelim questions. Other levels and Maths are in preparation. Tap "Notify me" on any topic and we will WhatsApp you when it is ready.

    How does the referral code work?

    Your order reference (for example TW-AB12) becomes your referral code once your order is paid. When another parent enters it in the order form, they get $2 off their first order, and we take $2 off your next order for each family who orders with your code. Your own code can't be used on your own order.

    Do you sell printed copies?

    Yes. A spiral-bound printed full P5 Science set is $89.80, delivered in Singapore. Ask us on WhatsApp to order one.
