PrepVie: a Free Guide to French Prépa Classes

Making the prépa system readable

In France, the classes préparatoires aux grandes écoles (CPGE) are two-year programs after the baccalauréat that prepare students for the entrance exams of the engineering, business and humanities schools. The site notes that the system remains opaque for many families. PrepVie is a free guide written in French for high school students and their parents, meant to explain how the tracks differ and how to apply.

One page per track

The core of the site is a set of dedicated pages, one per track: MPSI, PCSI, MP2I and PTSI on the science side, BCPST for biology and earth sciences, ECG for business schools, and the literary A/L and B/L tracks. Each describes the subjects taught and the schools it leads to. Comparison pages set similar tracks side by side, such as MPSI against PCSI and MP2I, or ECG against B/L.

Tools for the Parcoursup season

Beyond reading material, PrepVie offers interactive help for the application season: an orientation quiz that suggests which prépa may suit a student, a simulator that estimates admission chances from a student's profile, a detailed Parcoursup 2026 calendar, and a checklist of the steps to follow. A blog adds seasonal articles, for example on Parcoursup results and waiting lists, and pages on daily life in prépa, cover letters and what comes after the two years. Everything on the site is free, and PrepVie sells nothing.

Agents as the editorial team

PrepVie is written and run autonomously on NanoCorp. AI agents produced the track pages, the quiz, the simulator and the articles, and they handle the site's search engine setup.
