If you are currently navigating the grueling, gamified labyrinth that is 42 School (or one of its many global campuses), you know there is one hurdle that causes more sleepless nights than the others: The Exam.
Unlike the projects, where you can iterate, google, and ask peers for help, the exam is a locked-down, time-boxed crucible. You, a terminal, and a ticking clock.
But fear not. The 42 community is legendary for its solidarity, and the secret weapon for most successful cadets lives on GitHub. If you’ve searched for 42-exam github, you are on the right track. Here is how to use these repos without falling into the trap of "cheating yourself."
Common elements found in "42-exam" repositories include: 42-exam github
Repository structures vary, but a representative tree:
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.
[ ] first_word (handling spaces and tabs) [ ] ft_strdup (malloc error management) [ ] ft_strrev (in-place reversal) [ ] ulstr (case inversion) If you are currently navigating the grueling, gamified
Use this checklist one week before your next exam:
[ ] ft_atoi (including negative overflow) [ ] ft_strcmp / ft_strncmp [ ] ft_strcspn (custom implementation) [ ] print_bits (bitwise manipulation) [ ] wdmatch (string comparison with constraints)
To understand why 42-exam exists, one must understand the structure of 42’s evaluation. The exams are staged in levels (from Beginner to Expert). A student is given a specific time limit to solve a problem. If they succeed, they level up. If they fail, they are kicked out of the exam session and must wait until the next month. Repository structures vary, but a representative tree:
This creates a unique pressure cooker. The exams are pass/fail barriers that gatekeep the rest of the curriculum. Unlike a traditional university where a professor might offer a study guide or a review session, 42 offers silence.
The 42-exam repositories on GitHub stepped into this void. They are the "shadow curriculum." They document the algorithms that have appeared in past iterations—the notorious ft_printf variations, the pointer manipulation of count_islands, or the mathematical puzzles of print_hex. They categorize the exams by difficulty, offering a roadmap to a destination that the school purposefully obscures.
After you simulate an exam, have a fellow student grade you as if they were Moulinette. They will catch norm errors and edge cases you missed.
