What's the class schedule like? How long and how often are the classes? That's definitely going to be the biggest monkeywrench in any program you try to figure out.
We don't have much info to go on, but check out this article from the Figure Athlete site discussing this exact problem area:
I doubt that. Nothing personal, but it's very common for first-time competitors to underestimate the actual amount of bodyfat they need to lose in order to get into peak contest shape. In any case, base your progress on pictures. Try taking basic pics (full body front, back, and side) once or twice a week under consistent conditions (same clothes/lighting/empty stomach/etc.).
But really, these are all questions you should be asking your trainer. You're paying them, they see you in person (we're still waiting on that pic of you to really see where you're at), so they have the best insight so far. If you're not confident in their skills or you're not happy with the results so far, that's a whole 'nother issue.
