42-exam Github May 2026

Date: March 23, 2026

If you have an exam coming up, here is the GitHub-powered battle plan:

This is a sensitive topic. 42 enforces a strict "No Cheating" policy (Moulinette detects plagiarism). However, using GitHub is not cheating if done correctly.

The Wrong Way (Cheating):

The Right Way (Preparation):

The Golden Rule: If you cannot hand-write the code from memory on a blank sheet of paper, you do not truly understand it. Use 42-exam github repos to check your blind spots, not to replace your brain.

The real exam deducts points for norm errors. Your simulator should do the same. Before typing grademe, run: 42-exam github

norminette -R CheckForbiddenSourceHeader yourfile.c

If you see "Error," fix it immediately. Over time, you will internalize the norm (for loops without declarations, 25-line limits, 4-space tabs).

The term "42-exam" refers to a collection of open-source simulation tools and past exam training scripts created by 42 students, for 42 students. Since the official 42 exam environment is proprietary and only accessible on campus during exam sessions, the student community has built third-party emulators that replicate the exact behavior, grading system, and question patterns.

These repositories typically include:

The most famous and widely used repository is "42-exam" by jcluzet (or similar forks), but there are several critical ones you should know about.

The real exam bans functions like printf (you must use write), malloc in certain levels, etc. A good simulator enforces this. If yours doesn’t, manually check each time.

Many students focus only on C exercises, but the exam includes a Shell section (usually Exam Rank 01). Date: March 23, 2026

Repo: 42-exam-shell (Various authors) This collection focuses exclusively on awk, sed, grep, and bash logic. Most C programmers neglect the shell, but these are free points if you practice them. Do not skip this.

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