42 admissions / no leaked material
The Piscine is a month of learning, selection, and self-discovery.
The Piscine—French for swimming pool—is the immersive stage in 42 admissions. For roughly four weeks, candidates work through programming modules, peer evaluations, group projects, and regular exams while experiencing the school’s learning method from the inside.

What the Piscine is—and is not
The Piscine is not a conventional preparatory class, and it is not simply a month-long programming contest. It lets a campus observe candidates inside the method while candidates discover whether intensive, self-directed, peer-based learning suits them. The campus decides selection; no independent guide can provide the formula.
Before the month
The Piscine sits near the end of the application path.
The exact sequence and names differ locally, but candidates generally register, complete an online stage, attend an introduction or check-in, and then receive access to available Piscine sessions.
Places and dates change. A search result, forum post, or this page should never replace the application platform and current instructions from your chosen campus.
Inside the month
Projects create the need to learn.
42 Paris describes modules that focus on specific concepts, automated checks, peer evaluations, weekend group work, and regular machine exams. Lisboa and Porto describe a similarly intensive, project-based month with peer feedback and weekly challenges.
The point is not to arrive already knowing every exercise. The point is to work inside a system where new material keeps appearing and your response becomes visible.
Starting from zero
No prerequisite does not mean no difficulty.
Candidates without coding experience are welcome. Basic terminal familiarity or a small amount of C may reduce first-day friction, but a large private answer archive does not prepare you to explain, adapt, or recover when the next task changes.
Useful preparation protects the conditions for learning: clear obligations, realistic travel, simple meals, a minimum sleep plan, and a way to return after a bad day.
Selection
Do not turn community advice into a secret formula.
Official pages describe involvement, peer learning, projects, and the immersive experience. They do not publish a universal scoring recipe that an outsider can reverse-engineer for you.
Treat advice about one perfect schedule, project threshold, social style, or admissions trick as anecdotal. Participate honestly, follow the campus rules, and make decisions that preserve your ability to learn.
Local preparation
Lisboa and Porto deserve separate practical plans.
The learning principles travel across the network; transport, dates, city costs, campus communications, and your actual obligations do not. That is why this site keeps separate Lisboa and Porto preparation pages.
Both offers focus on mindset and life organisation. Neither includes admission influence, current project solutions, exam answers, or private material.
Comparison
Piscine feature, practical meaning, and preparation boundary
| Official feature | What it means in practice | Useful preparation | Boundary |
|---|---|---|---|
| Intensive month | The rest of life competes for limited attention | Calendar, transport, food, sleep, communication | No schedule guarantees selection |
| Project modules | New concepts appear through tasks | Terminal basics and a repeatable research loop | No leaked or current solutions |
| Peer evaluation | You explain and review work | Practice specific questions and clear explanations | Do not trade finished answers |
| Group work | Coordination becomes part of the task | Listen, state assumptions, divide work visibly | Do not erase another person’s learning |
| Exams | Independent recall and problem-solving matter | Rest, review fundamentals, practise under a time limit | No exam content or prediction |
Local preparation
The Piscine happens inside a campus and a real life.
The Lisboa and Porto pages cover local practical decisions and independent mindset and life-organisation support.
Common questions
The Piscine is a month of learning, selection, and self-discovery.
How long is the 42 Piscine?
Most official 42 pages describe roughly four weeks or 26 intensive days. Confirm the exact dates and attendance expectations with your campus.
Do I need to know C before it starts?
No prior coding experience is required. The Piscine commonly introduces C through practice, so a small amount of public beginner preparation can reduce friction without trying to pre-complete private work.
Is the Piscine a bootcamp?
It shares the intensity of a bootcamp, but its main role is immersion in 42’s method and selection for the curriculum rather than selling a standalone course.
Can I work during the Piscine?
Campuses describe it as a full-time experience. Some people have unavoidable obligations, but you should calculate fixed hours, travel, meals, sleep, and recovery before assuming both will fit.
How are candidates selected?
The campus owns that decision. Official sources describe the immersive process but do not provide a universal formula that independent coaches can promise to optimise.
Can I use AI or copied solutions?
Follow the current campus rules. From a learning perspective, any tool becomes harmful when you cannot explain, test, or reproduce the result yourself.
What happens after the Piscine?
Candidates who are selected begin the common core at the campus connected to their application, subject to the campus’s current start rules.
