Moving up to Primary 4
- Cover at least 80% of this Level's knowledge points, with at least 50% of them mastered (confirmed by spaced review, not one good day).
- Pass 2 full-length practice exams on different papers, at least 7 days apart, within 60 days.
- Answer at a steady pace: a median of 65 seconds a question or less.
- Or, when the signs are there, take the next Level's entry check: 75% or more moves up straight away.
A sample question from Primary 3
Library stickers come in sheets of 5. Hugo has 18 sheets. He wants an easier problem with the same answer as 18 × 5. Which problem should he use?
Answer: 9 × 10
Worked solution
- Half of 18 is 9. Double 5 is 10.
- Halving one number and doubling the other keeps the answer the same.
- 9 × 10 = 90, and 18 × 5 = 90 too.
Read-only. Every other question opens after sign-in; each child's first round is free.
Questions families ask
- What does Prep cover for ISEE Mathematics Achievement?
- Primary 2, Primary 3, Primary 4, Lower Level, Middle Level, Upper Level. Each Level has its own chapter map, practice rounds, sealed practice exams with every answer and worked solution at the end, and a published gate to the next Level.
- When is the next ISEE Mathematics Achievement date?
- The next official date has not been announced yet. We update the page as soon as the organizer publishes it.
- How much does it cost?
- Each child's first round and its summary are free, with no card needed. After that, a Series pass is $14.99 a month for the whole family (up to 5 people) and covers every Level of the Series, so moving up never meets a new paywall.
- Does Prep guarantee a score?
- No. Prep shows exactly what your child has mastered, what comes next and when they are ready for the next Level. Nobody can promise a contest result.
