Honestly? I suggest being honest about it. Don't bullshit your way through it and make it look like you can do everything, you'll get asked about doing it and you'll seize up and that'll look really bad, never lie in interviews. Be honest about it.

All interviews are different. Some will stick to things about the course, some will include personal questions such as siblings etc etc. The main questions will be things like why do you want to take the course, why you should get accepted kind of things. You can't really study for an interview. :p

Like Laim said be honest about everything, also for my interview 2 years I was asked on why I am doing those courses, if I will continue to do them in Uni and how they will influence my future career path and had to also explain what exams I would have to take to become a Chartered Accountant. So keep that in mind and good luck.
