Checking your account…
Parent sign-in
Sign in with your Google account to manage learners and their passwords. Each learner gets a U13 student login ID automatically.
Continue with Google →Local demo: sample parent account, stored in server memory. No Google sign-in or real email is used. Results disappear when the demo server restarts.
Finish creating your parent account
Review these choices before adding your children. Email updates are optional; you can untick the box now or change the setting later.
Your learners
Administration ↗Only the signed-in parent account can add or remove learners. Enter a learner’s name or nickname. We create a unique @under13.com login ID; it is not an email inbox. You set and can update their password. No date of birth or school is needed. On a shared device, sign out of the parent account when you’re finished.
Recent practice results
Practice results are submitted by the game, not a formal assessment. Completed maths, algebra and science rounds are saved. The first two Basic Maths levels have no waiting. Later free-package levels have a five-minute wait across non-exempt activities. A parent account manually marked paid has no reattempt waiting.
