WEI
You can now pre-register for the WEI on our website http://wei-cs.fr.
To do this, go to the site and register using the personal space tab. Once registered and logged in, you can access the pre-registration form in your personal space. All you have to do is fill it out and read the rules for your pre-registration to be validated.
Feel free to browse the whole site, which contains a lot of information about the first two weeks and a list of things to bring when you arrive.
