42 is a network of tuition-free computer science schools. it started in paris and now has campuses in many countries. there are no traditional lectures in the usual sense: you learn by doing projects, with peers, and by figuring things out yourself. the curriculum is structured as a path of skills and challenges rather than semesters and exams in the classic mold.
admission is selective. people often go through a trial period called the piscine—intense weeks of exercises and collaboration that show whether you can learn under pressure and work with others. the school is funded so that students are not paying tuition; the idea is to remove money as the gate to becoming a developer.
the name comes from “the answer to life, the universe, and everything” in hitchhiker’s guide—a nod to curiosity and depth, not to a single fixed recipe. campuses share a philosophy: peer-to-peer learning, responsibility for your own progress, and a lot of time coding on real problems.
what it means to me
for me, 42 was the first time i left home to live somewhere else and fully commit to coding. i met people who cared about building things and getting better every day. i had to unlearn bad habits and learn again from the ground up—in c, on unix, with deadlines and collaboration that felt closer to real work than anything i had done before.
it wasn’t only about syntax. it was about persistence, asking for help, giving help, and trusting that you can solve what looks impossible if you stay with it long enough. robotics competitions and team projects there shaped how i think about hardware and software together.
that period is a big part of why i still want to build real things in the world—not only apps on a screen, but systems that do something physical or useful outside the classroom.
