How PhysicsGraph Works
A complete learning system designed to maximize your understanding per minute of study time. From diagnostic testing to AP exam preparation, every piece works together.

Knowledge Graph
The core innovation that powers everything. See exactly what you know, what you need to learn, and the most efficient path forward. Skip prerequisites you already understand, and never get lost in a sea of unrelated concepts.

Lessons
Each lesson is designed for 5-15 focused minutes. More diagrams than a textbook can fit, immediate practice problems, and you're always prepared because we ensure prerequisites are mastered first.

Diagnostic Test
Already know some physics? Our diagnostic quickly finds your knowledge frontier so you can skip what you know—without jumping so far ahead that you struggle. 30 minutes can save hours of redundant studying.

Multi-Step Questions
Real physics problems don't come in single steps. Tackle complex scenarios broken into 4-10 guided steps—tracking objects through multiple phases, assembling equations, and combining concepts like you'll need when it's time to use your physics outside the course.

Free Response Questions
FRQs are 50% of your AP exam. We offer dozens with accurate AI grading in ~1 minute, detailed point-by-point feedback, and coverage of all AP question types and Science Practices. Human regrade available if needed.

Motivation & Gamification
Game companies spent decades learning how to keep people engaged. We use those same techniques—XP, progress bars, daily goals, and visible knowledge graph progress—to make learning feel rewarding, not draining.

Adaptive Review and Spaced Repetition
Remember what you've learned efficiently by reviewing at the exact optimum time. PhysicsGraph improves on the standard spaced repetition system by using the knowledge graph to detect implicit review.

Practice Exams
Take our practice exams under test conditions to figure out how you perform for extended periods of time under pressure. Pinpoint weaknesses, increase confidence, and be completely prepared for exam day.

Score Guarantee
We guarantee you a 5 on the AP Physics 1 exam if you complete our course. No other online platform guarantees this. We let you complete our course any time before test day, at your own pace, and you get as many tries as you need.
Everything Works Together
The Knowledge Graph is the foundation—it tracks what you know and determines the optimal learning path. When you start, the Diagnostic Test quickly maps your existing knowledge so you don't waste time on basics you've already mastered.
As you progress, Lessons teach concepts in focused, digestible chunks with immediate practice. Multi-Step Questions at the end of each unit challenge you to combine concepts like you'll need to on real exams.
For AP test prep, Free Response Questions with instant AI grading give you the practice you need for 50% of your exam score. And throughout it all, Gamification elements keep you motivated and coming back.
The result: higher scores in less time, without ever feeling lost.
