Should I bother applying to Berkeley?

Should I apply to UC Berkeley if I have a 3.9 and a 1300 SAT score?

Is the 3.9 GPA, your capped weighted UC GPA or Fully weighted UC GPA? https://rogerhub.com/gpa-calculator-uc/

Also what is your correct GPA and test score information? You stated on another thread a GPA of 3.8 and SAT of 1310?

Here is some UC statistical data to help gauge your chances. Remember admissions for the UC’s are not just about stats but also your EC’s and personal insight essays. If you want to apply, then definitely apply just consider it a Reach school and it never hurts to have a few Reach schools on your college list.
