Prépa 210: the same engine, a second test.

The twin of Prépa 600, for the TAGE 2®, the test taken by two-year graduates entering the third year of French business schools. A free mock test with its report, then 19 mock tests for €39, paid once. Same engine, same account for the student, 0 server functions added: the second site went live the day of its first file.

One style sheet, one engine: the accent changes, the rest is shared.

What is shared

One engine, two storefronts.

The same repository, the same deployment, the same database and the same checkout serve both sites. A student registered on one is registered on the other. What changes fits in two files: the test, and the brand.

Server functions are counted in the repository, each with its birth date: all of them predate the first file of Prépa 210. The second site added nothing to the server, only a test described in one file and a brand described in another.

19 September 2026

From the first file to the site online: one day.

Prépa 600 took 6 days from the idea to the first user. Its twin had no engine left to build: the hours below are the repository's.

  1. The first file.A second site declared: a brand, a domain, a test.
  2. The domain connected.prepa210.com was serving the other site's home page; a façade fixes it.
  3. The green icon."Otherwise you can't tell it from the other one."
  4. Two search pages.What people type before looking for a prep course.
  5. The bank audited.Every question form compared with the official candidate booklet.

The next morning, the bank grows from 5 to 20 mock tests and the price settles at €39. Repository times, Paris time zone.

What the candidate gets

70 questions, 115 minutes, a score out of 210.

The official TAGE 2® format, read on tage2.fr and in the candidate booklet: six sub-tests in three dimensions, 4 options per question, 3 points per right answer, no penalty. The engine reads this format from one file; the mock test plays like the real one.
