uc berkeley supplemental questionnaire, HELP!!!

<p>i just received this supplemental questionaire...what are the stats on the students who recieved it and got accepted...</p>

<p>my stats are far below from those applicants of uc berkeley, thats why i was suprised that i even got one....is this a good thing?
my gpa is 4.13,
1650 SAT
22 ACT
my parents make 24k
1st generation to attend college.</p>

<p>since they ask you for ur first semester grades of ur senior year, do you think that they will take this gpa and combine it to ur 10th and 11th grade gpa? because my senior gpa is 4.5</p>

<p>and how long should the asnwers be, is there a limit?</p>
