How PrepGraph helps K-12 learners
Goal-driven
Set your grade target and PrepGraph builds a personalized path across every subject.
Finds gaps early
Diagnoses weak concepts before they show up on report cards or assessments.
Tells you what to study next
Every day, clear guidance on what to focus on — no more guessing.
AI tutor, always available
Explain, then prove it: when you are stuck the tutor shows the worked step, then asks you to do the next one yourself; when you are close, it asks before it tells.
What a session looks like
A student opens PrepGraph with the homework or the unit they are working on. The tutor asks what they already know, explains the next step out loud and on a whiteboard, and checks the idea with a similar problem before moving on. It does not hand over answers to copy: every explanation shows the working.
Between sessions, PrepGraph keeps a map of which concepts each student has mastered and which are slipping, and brings the slipping ones back for spaced review before the next quiz or unit test.
Subjects and standards
PrepGraph covers grades 6–12 in Math, Science, English and Social Studies. When students sign up, they choose the standards their school follows — Common Core for math and English with NGSS for science, or the California, New York, Texas (TEKS) or Florida (B.E.S.T.) state standards — and their practice is organized around that framework, in the order and vocabulary their classes use.
In high school the same tutor carries on into test prep, then college and career skills. A student preparing for the Digital SAT or the Enhanced ACT can set that test as their goal and get a plan that works back from the test date: see PrepGraph for the SAT and PrepGraph for the ACT.
