Should I learn off set phrases on each topic? What's the best approach to doing well in the oral exam?
I find that writing all your notes out for each topic on flashcardsis really helpful; but you should also memorise the notes if you can and say them out loud as much as possible! :)
Learn a paragraph for each topic and then it helps if you can practice with a French speaker, even a friend who can ask you the questions on the topic so as to get you used to speaking. Skype works great for orals in my opinion, it's less time consuming that meeting up with someone but you still get used to talking in French
