The campus can be reached from the train station (Lille Flandres) using the Metro, direction 4 cantons. Get off at "cité scientifique". When leaving this station, turn back and walk along the Metro, until you see the "M1 Mathématiques" building on your right. The "M2" building is right behind that one.
Lunches may be taken at "Restaurant Universitaire Barrois" on the campus.
There are no registration fees.
