What matters most? GPA, EC's, Recs, Test Scores?

A transfer application consists of a college GPA, high scool GPA, college ECs, high school EC’s, and professor recommendations. Which one matters most? Should first semester transfer applicants retake standardized tests?

@Catz1997 It highly depends on the school you are applying to. Even schools within the same network may have different values (UCSD vs UCLA or UCB for example).

Depends on which university. But college transcript is the most important part in most, if not all, university decisions.

All of the above.
