Turn physics study from “more questions” into a visible learning path.
Build structure with knowledge maps, diagnose gaps with targeted practice, then close the loop through homework and teacher feedback. Built for AP, IGCSE, A Level, and competition physics.
One continuous learning system
Knowledge Map
See the course structure, unit sequence, and key concepts before practice becomes a collection of disconnected questions.
Practice Library
Target questions by curriculum, unit, question type, and difficulty. A public sample is available without signing in.
Homework & Feedback
Keep assignments, attempts, and teacher review in the same learning loop instead of scattering them across messages and files.
A learning loop, not just a question bank
Use the Knowledge Map to understand what comes first and how ideas connect.
Use targeted questions to expose specific conceptual, modelling, and calculation gaps.
Keep attempts, assignments, and teacher feedback so improvement stays visible over time.
Pocket Cosmos is designed around the actual cycle of one-to-one physics tutoring: what to teach, what to practise, what to assign, and what to revisit next lesson.
