You should definitely learn some nice phrases about hobbies.
For example, the phrase 'to be keen on' means 'to like'.
What are your hobbies?
I'm keen on gardening.
How about holidays? In the FCE exam you should know the difference between 'travel', 'cruise', and 'flight' - you could easily use these words if asked about holidays.
What sort of holidays do you like?
I'm actually not too keen on travel, and I really hate flights. I like cruises, though. That's my favourite.
Get the idea? As I said before, you're not learning whole speeches, just a few words you can use at the right time.
