What are my chances of getting into UCSD?

I have a 3.7 unweighted gpa and 4.2 weighted. I’ve taken honors and ap classes throughout high school but I haven’t passed an AP test yet. I’m in a lot of extracurricular activities, including sports. My act score was: Composite-25, English-24, Math-23, Reading-26, Science-25, English Language Arts-25, Writing Subject-24. Yes I’m aware that I could have used cappex to see my chances, but I trust people with experience more than a website, and I’m really worried I won’t get in.

What is your UC GPA? http://rogerhub.com/gpa-calculator-uc/

With your GPA is within range, but ACT is low. UCSD looks like a Low Reach.

UCSD’s most recent 25%-75% ACT range was 26-32, so it’s most likely a reach unless you have extenuating circumstances, such as low-performing high school, socioeconomic challenges, first-generation college student, low income, etc.
