Write key phrases (both basic and sophisticated) on flashcards that you can form answers around as I found that simply memorising answers can lead to freezing and blanking if you forget the whole answer! This can also combat unexpected questions that may pop up and help you show a wide range of vocabulary which will get you high marks. Listening to French radio too will help you improve your accent without you even knowing you're learning.Learn lots of vocabulary and I suggest even making a list in English of answers to certain difficult questions as I found that most of the time I was struggling because I could not think of what to say nevermind in French! Family shooting you random questions in French when you least expect it is a great way to overcome feeling put on the spot. If memorising is still high on your agenda I found reciting it during an activity like juggling or keepy uppies is great fun and if you can do it then, then the exam won't be a problem!
