As for UNIL, they have 3 offerings. As per their web site here is the info.,
(
www.unil.ch/fle)School of French offers, during the academic year, courses in French language, literature and civilisation, as well as training in language teaching. Beginners are not accepted. Therefore, as a minimum requirement, your French language skills must be good enough to allow you to take part in everyday conversation and to understand and write a variety of simple texts.
Organised every year during the University vacations in summer and winter, the Cours de vacances (Vacation Courses) (
www.unil.ch/cvac) offers courses in French language, literature and civilisation are intended for non French-speaking students of different levels: complete beginner, beginner, intermediate and advanced. No preconditions need to be met. These courses are particularly recommended for non French-speaking students intending to study at the UNIL. Fees for these courses are to be paid by the students themselves.
The Programme Tandem (
www.unil.ch/tandem), a simple yet efficient method for improving foreign language skills, is organised as follows: two people whose mother tongue is different agree to meet on a regular basis and teach each other their respective languages free of charge. The partners are completely autonomous since they decide where and how often they will meet, what form their meetings will take, and how they will correct each others' mistakes.
