About this app
PathStem turns math, physics and computer science into one connected learning path with 18,000+ practice questions, built for AP Physics, SAT prep and college-level STEM. Pick a themed roadmap built around a real skill and follow a clear sequence instead of guessing what to study next.
WHY PathStem
Structured roadmaps. Choose from 15 themed roadmaps across math, physics and computer science, each built around a real skill like Understand Space and Motion or Teach a Machine to Learn, or explore freely with no guided path. Each roadmap sequences topics the way a real course would, foundations first, advanced ideas later.
362 topics, explained properly. Every topic walks through a starting question, the core idea, a visual diagram, a precise definition, a worked example, common misconceptions and real-world connections, not just a wall of text. This is a STEM learning app built for understanding, not memorization.
18,000+ practice questions. With many practice questions per topic, there is always another angle to test your understanding from, whether you are doing quick daily practice or curricular physics prep before an exam.
46 hands-on projects. Simulate a figure skater's angular momentum, model rotational motion, or work through a real system design style build, PathStem is a STEM projects app, not just a quiz app. You read the setup, follow real steps, and mark your own result.
Spaced repetition that adapts to you. PathStem uses FSRS, a modern spaced repetition algorithm, to resurface topics right before you would naturally forget them. Rate how well you remembered each one and your review schedule adjusts automatically, the same mechanism behind the best flashcard and memory retention apps, applied to real STEM depth instead of flat flashcards.
Built for daily practice. A Daily Challenge keeps a streak going with just one focused question a day, and the Review tab always shows exactly what is due today, nothing more, nothing less.
WHO PATHSTEM IS FOR
Learners tackling AP Physics, SAT math prep or college-level math and physics courses. Self-learners working through computer science fundamentals outside a classroom. Anyone who wants a structured, visual, hands-on alternative to scattered videos and disconnected practice sites.
HOW IT WORKS
Unlock topics by watching a short ad, or remove ads entirely with a one-time purchase. No subscription, no recurring charge, ever.
Start with any roadmap, or explore every topic freely. Either way, PathStem is built to make learning math, physics and computer science feel like following one clear path, not juggling ten different apps or websites.
