Berkeley and Yale, two B+'s sophomore year, chances?

I’m a sophomore and I have two B+'s. Last year I had all A/A-'s, so I was wondering what my chances are going to be if I have all A/A-'s next year. For Yale?
Berkeley?

(My ECs are dance, abacus, volunteer,and an internship)

There are several online tools to help you calculate your UC GPA and chances of admission.

Your EC’s don’t have enough info. How long have you danced? What level? How many hours of volunteer work? What was the internship?

In addition - test scores? Awards won?

Two B’s won’t prevent you from getting into Berkeley, but your overall application has to be considered and how your UC GPA compares to other applicants.
