In my first-year French classes, on the day before a test, I usually spend forty to fifty minutes reviewing. Since the students have learned a lot of new material over a period of perhaps two weeks, their knowledge may need refreshing. There are a number of exercises one can do and it is advisable to review as much as possible and resort some of the time to questions similar to those in the upcoming tests. The quickest way to review effectively is through very simple translation into the target language.
