Hi,
revision is different for everybody-some people find reading their notes over and over again helps them to memorise facts whilst others need to visualise something-or draw it. I am also studying French and I find that a very helpful technique is to read French books ,watch French movies and listen to French music.Whilst you may not understand all of what is going on, it will be helpful to hear how the French speak in general.In the class we are taught much more slowly however the exam is spoken much more faster and you have to pick out words, which lead to the answer.In the terms of revising for a certain topic-practise reading over words-if you have any members of your family that speak or French or even if you are studying it with a classmate- have a discussion in order to familiarise yourself with the words and content.
hope this helps
