Hi I am a junior in highschool.

AP literature - B/B
AP Calculus (AB) - A/A
AP US History - A/A
Band - A/A

Heritage Chinese 3 - A/A
the 2nd semester here is what I think I will get from what I got 1st semester
Summer after junior year :
Calculus (BC)(college course) - A

Estimated (self calculated) GPA : 4:15
I am not too sure if this is right, but this is how I calculated it :
A - 4/5 pts depending on regular/(ap/college) courses
B - 3/4 pts and so on
Formula : (total pts from UC gpa standards (a-g courses summer after freshman to before senior) and divide that by the # of classes) – brief – (total pts/#classes)

SAT : 730 math
680 critical reading
630 writing

SAT2 : physics 800
Math 2 800

Ethnicity : Asian/pacific islander

ECs : 1. varsity/frosh Track all years and 2 years of XC

  1. I was involved in some volunteering do to being an officer of a volunteering club
  2. AMC/F=MA competitions (participated but did not win anything/etc.)
  3. Made a game on a platformer called ROBLOX with over 55,000 plays. Accepted to the company's private developing forum.

Clubs : 1. Leo club (volunteer club) officer position

  1. Math club
  2. Physics club
  3. Computer science club (did not do much)

I am not sure what else I could give about the info of my stats, but my question is : what do you guys think my chances are to any of the UCs and what I can do better to make my app more impressive for a CS major? I am a californian resident.

UCs desired : UCLA,UCB,UCSD,UCSB,UCD,UCI
