Searching for "42-exam" on typically leads to two types of resources: practice simulators that mimic the real exam environment and solution repositories containing past exam questions Recommended GitHub Practice Simulators To prepare effectively, use tools that recreate the experience. 42_examshell by terminal-42s : A comprehensive simulator for Rank 02 through Rank 05
Since you can't access GitHub during the actual exam, these repos are for pre-game prep. The best ones explain the logic behind tricky functions like ft_split or the bitwise operators, rather than just giving you a snippet to copy. The Danger of "Copy-Paste" Learning
When a student eventually passes their final exam and leaves the "Piscine" behind, they often look back at that GitHub repo not as a crutch, but as a companion. It was the silent partner in their journey from novice to developer—a monument to the collaborative spirit of coding, existing in the shadows of a system designed to test solitary resilience.
The most famous resource is often titled 42-exam-rank-02 or grademe. These tools allow you to run a script in your terminal that behaves exactly like the real exam: It gives you a random assignment. You must code it within a directory. You run a command to "grade" it.
This is the first major hurdle for most. Search for repositories that include the common "Level 1" to "Level 4" folders. Look for those that have clear explanations of: ft_printf (Simplified version) get_next_line (Exam version) Basic logic puzzles like max or swap_bits 2. The Exam Simulator (Grademe)

❌ Ignoring the "Forbidden Functions" List
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.
- README.md — overview, prerequisites, usage, disclaimers.
- Directories per subject or project (e.g., piscine-day00, ft_printf, libft, get_next_line).
- Solutions: source files (.c, .py, .sh, .js), often with comments or minimal obfuscation.
- Test suites: unit tests, shell scripts, Makefiles, expected input/output samples.
- Automated checkers: scripts to compile, run, compare output, or simulate campus checkers.
- Utilities: template Makefiles, header files, helper functions, CI configuration (.github/workflows).
- Metadata: issue trackers, pull requests, tags like [42], [exam], [piscine].
- Licensing: often missing, ambiguous, or permissive (MIT, Unlicense) regardless of content origin.
- Large forks and aggregates that mirror many student solutions.
Ignoring Forbidden Functions: GitHub solutions sometimes use functions that are forbidden in the actual exam. Always cross-reference the subject file in the repository.
