Questions about Bard High School Early Collage..?

I normally get between 90-97% average in 7th grade. I'm also in a regents track, do many extra-curricular activities, and am considered a gifted student. I ROCK at writing essays, and think I can do well in 24 question math part of the test. First of, based upon this 1-do you think I will get in? 3000-4000 students apply, and only 135 get selected. 2-any advice for the math section? How hard are the questions? Should I study 8th or 9th grade math? 3- What was the test like? Can anyone help me with the interview part?
