Can I participate?

You must be at least 14 years old. No need to be a student, but students and professionals compete in separate categories.

What should I bring?

Your good mood! Nothing is needed - we will provide your team with a computer, pen and paper.

Where is it?

HC2 is in the CO building at EPFL.
You can find directions here.

What about food?

We will provide you with breakfast and lunch; you can optionally join for dinner for CHF 15 more.

What if I don't have a team?

Don't worry! Register as a single participant, and we'll try to find you a team. You can always participate alone, of course.

I have another question...
