Why you need it:
You wouldn't run a marathon without ever practicing on pavement. This tool lets you practice the mechanics of the exam:

How to use it (ethically):
Clone it, run ./install.sh, and take a mock exam once a week. Do not look at the source code for answers until you have legitimately failed an exercise. The goal is to train your muscle memory for the terminal workflow, not to memorize code. 42-exam github

Simply cloning a repo will not help you. Follow this 3-week preparation cycle.

Public "42-exam" GitHub repositories present educational value but also significant risks to assessment integrity and student outcomes. A balanced approach—combining detection, thoughtful assessment design, clear policies, and provision of legitimate learning resources—reduces harm while preserving community knowledge sharing.

However, there is a valid critique of the 42-exam ecosystem. The most famous repository in this niche is

Some iterations of the repository contain "grademe" scripts—automation tools that can test code against the exam checker. While useful for debugging, this creates a dependency loop. Students stop reasoning through their errors and start playing a game of "trial and error" with the compiler.

Furthermore, the temptation to simply copy-paste solutions from the repo into the exam terminal is real. Students who take this path usually pass the exam but fail the core curriculum later, as the concepts they bypassed (like recursion or memory management) are foundational to future projects. The 42-exam repo acts as a crucible: it offers the tools for success, but it also offers the rope to hang oneself. The student determines which tool they pick up.

The best way to internalize the material is to build your own private 42-exam repository. Do not just clone—create. How to use it (ethically): Clone it, run

mkdir my_42_exam_lab
cd my_42_exam_lab
git init
mkdir level_0 level_1 level_2 level_3 level_4

Then, for every exercise you master:

By building your own repo, you transform from a passive consumer of 42-exam github resources into an active creator. This is exactly what 42's pedagogy intends.

Simply cloning a repository is not enough. You need a training methodology.
