Epsilon : Maths Physique Prépa

Epsilon transforms wasted time—the train ride, the cafeteria line, the five minutes before the oral exam—into meaningful study time.

A FEED, NOT A TEXTBOOK
Open the app, scroll: definitions, theorems, common pitfalls, methods, and quizzes unfold in full screen, in an order designed for memorization. Each card gets straight to the point: an idea, a formula, a reflex.

100% OFFICIAL CURRICULUM
All content follows the official CPGE (Preparatory Classes for the Grandes Écoles) science curriculum, chapter by chapter, in the correct order. No anecdotes, no extraneous material: each card could appear in the oral exam.

• MPSI Mathematics: the complete syllabus in a thousand flashcards
• MPSI Physics: chapters currently being published
• Other tracks (PCSI, MP, PC, PSI, PT...) are coming soon — the complete catalog is already available in the library

DESIGNED FOR PREP SCHOOLS
• Formulas rendered in true LaTeX, readable on mobile
• Works entirely offline, on the RER (suburban train) or in the dorms
• No account, no ads, no data collection: your revisions stay on your phone
• Star a flashcard to find it in your favorites
• Track your progress by subject and your daily schedule

Epsilon is developed for prep school students, with one obsession: rigor. Found an error on a flashcard? Write to us: [email protected]
