That is very true... it would be nice if at least at this forum everyone share his speaking and writing questions.... That would be a good help
Speaking had two parts:
(1) They gave us a made-up ad from a newspaper, asked us to "call them" and ask for more information; pretend we would need their services (I believe it was a financial organization) so you have to imagine the situation, the context and ask your questions.
(2) This part may be a little more difficult for some as it involves more of a daily type of conversation. I, as their friend, had to convince them to buy a product. They don't go easy on you. They had a response for every possible argument I had, but we ended the conversation on a good note. If you have any French speaking friends, I guess you can practice with them.
Writing had two parts as well:
(1) Write a short article for a newspaper. They gave us the second header of a minor news item (type "fait divers") and asked to use newspaper language + imagine the rest of the story. In general my only advice would be not to dwell too much on this first part (I lost way too much time & only noticed the second part later.) I would even consider starting with the second part, as it has more points.
(2) Ugh. Essay on a social subject. They don't judge your ideas, just the way you convey them. They asked us to discuss both sides of the subject (it was something about tangible / intangible cultural heritage.) I wrote down my ideas in bullet points in a rough first draft, then had to pretty much stitch them together as I wrote the final essay - I would have ran out of time if I tried to write it down properly. (Again, the first question's fault, not mine!) Anyway, make sure you have your Introduction - Développement - Conclusion, et voilà. Easy peasy.
Hope this helps. Good luck!
