I never studied in french before and completed my undergrad at McGill and Master' at Queens . My writing french is not the best as i was never schooled in french. On the other hand, my oral french and comprehension is pretty good as I have been living in Montreal my whole life. It's an easy exam if you are able to read and comprehend texts in french and recognize basic spelling mistakes you should be fine. I got a really good grade yet, i wouldn't consider myself as being very good in french. If i were you i would buy the TFI textbook which has examples and is very similar to the exam. Secondly, try reading books in french or the newspaper to recognize how words are written and used. if you prepare and follow the advice above i think ou should be fine.
