I actually emailed UCSD about my rejection and asked if I could send an appeal for them to re-consider me for an interview and this is what they sent me:
Hello XXX,
If an applicant does not receive an interview, it is because they are not academically competitive. We recommend that applicants have at least a 3.3 GPA. Applicants should keep in mind that last year's incoming class had an average 3.66 GPA. In order to improve their GPA, students can either retake classes they did poorly in (we will look at the average grade), or take additional upper division science courses. It is strongly recommended that students take upper division courses in biochemistry, physiology and cellular and molecular biology. These courses will better prepare students for the rigorous curriculum provided at UCSD.
Thank you,
