Which UC's can I get into with a 2.9-3.1 GPA?

well, GPA isn't too hot, but your SAT score is decent and you have a lot of extracurriculars that look great, but then again theres also the suspension problem. I'd say you have a good shot at getting into UCD, UCM and UCR for sure. Don't worry about it too much, just make a killer personal statement and pick a teacher who loves you to write the rec and i'm sure you'll be having a grand time at a UC in the fall :]
