Every idea in science stands on ideas you already know.
Science Path breaks high school physics, chemistry, biology, and earth and space science into small knowledge points. You learn each one after its prerequisites, and you review it before you forget it.
How it works
Placement test
A short adaptive test finds what you already know. Each answer tells us about related knowledge points, so you do not repeat what you know.
Daily practice
Each lesson teaches one knowledge point with a short explanation, a worked example, and four questions. A new lesson opens only when its prerequisites are mastered. Each lesson has its own XP: 1 XP is about 1 minute of work, so a longer lesson gives more XP.
Review and assessment
Mastered knowledge points come back for review at longer and longer intervals. A regular assessment checks a mix of them and schedules a review for each one you miss.
Parent and child accounts
A parent creates an account with an email address. The parent then adds an account for each child, with a username and a password. The child signs in with the username and learns. The parent sees the progress of each child, but does not learn on the parent account.
What the shapes mean
The same shapes mark each knowledge point on your progress map: a filled disc is mastered, a disc in a ring is due for review, an open ring is ready to learn, and a square is locked until its prerequisites are mastered.
