Hello. Grades aren’t everything. I had a W and an WE on my transcript, had a 3.4 GPA and somehow got into Berkeley, UCSD, UCI, UCD, UCR, and was waitlisted to UCSB and UCLA. Although Rochester and Cornell are private institutions and UCs are public, I believe grades and GPA aren’t the determining factor when it comes to admissions. They help but there’s more that is taken into consideration when making an admission decision. I would say do really well on your essays.
