GATES scholarship HELP!!!!

<p>hi, can anyone help clarify some questions for me? since its break and i have no contact to my counselors and the deadline is quickly approaching!!
ok. so..
cummulative GPA= GPA for 10+11th? or 10-12??
So if my school goes by a semester schedule, and i have two final grades per class, so i take 3 classes for the first half of the year and 3 other for the 2nd half. How would i report that?? since i get 2 grades, but the award thing only asks for 1 grade...do i just take my last final grade?
Is it mandatory to report classes u took over the summer?
a semester= 1/2 year?? or a term = 1/2 year?
last question: the thing asks for a maximum of 7800 letters per essay. that is A LOT of letters, my 600 words UC essay is only 4500 letters, so how much should i write here??</p>
