Anybody get in with a UC GPA 3.7-3.9?

Scan through last years thread to give you an idea although not an overall representation of the students accepted.
What is your unweighted GPA? You can use the UCSD common dataset to see where you fall in the enrolled students:

See section C11. Remember applicants with lower GPA’s are usually hooked: Recruited athletes. Special circumstances etc…
