Terms of use

Version of 11 October 2026

What changed on 11 October 2026

  • “Who can use Purrfect Marks” now covers a child signing in on their own device with a login code, and a second guardian joining with the approval of the parent who added the child.
  • “What Purrfect Marks is” now mentions assignments and rewards: points, badges and streaks are for encouragement only and have no money value.
  • “Ending or changing” now says how to delete a child or close your account yourself in Settings, and what happens to a child who has a second guardian.

These terms apply to Purrfect Marks, a free practice site run by Joshua Koh (JK) as an individual. By setting up an account, a parent or guardian agrees to them for themselves and for the children they add.

Who can use Purrfect Marks

A parent or guardian creates the account and adds their children. Children use Purrfect Marks under the parent's account and supervision. A parent is responsible for the accounts and children they add.

A child may sign in on their own device with a login code a guardian makes; keep codes private and sign a device out on the child's page if it is lost. Another parent or guardian may join a child with an invitation code, but only after the parent who added the child approves; that parent can remove them at any time.

What Purrfect Marks is

Practice questions, timed mock papers and tests written for Purrfect Marks, following the MOE syllabus and the PSLE format. Purrfect Marks is not run by, or connected with, MOE or SEAB. Results, including mock paper and test scores and mastery levels, are for practice only and do not predict exam grades.

Some questions are marked as trial questions: they have been checked automatically but not yet by a teacher. If you think a question is wrong, please report it with the warning-triangle icon.

Guardians can set assignments for their children. Points (XP), levels, badges and streaks are for encouragement only: they have no money value and cannot be exchanged for anything.

Using it fairly

Use Purrfect Marks for personal learning. Do not copy, sell or republish its questions, try to break or overload the site, or use someone else's account.

Content

The questions, solutions and site are owned by Purrfect Marks. All rights reserved. Notes and drawings a pupil makes stay theirs; we keep them only to show them back.

No guarantee

Purrfect Marks is free and provided as it is. We work to keep questions correct and the site available, but cannot promise it will always be free of errors or interruptions. As far as the law allows, we are not liable for any loss from using it.

Ending or changing

A parent can delete a child, or close their whole account, at any time in Purrfect Marks (Settings and each child's page) or by emailing us. If the parent who added a child closes their account and the child has another guardian, that guardian keeps the child; otherwise the child is deleted too. We may change these terms; if a change matters, we will ask parents to accept the new version. We may suspend accounts that break these terms.
