OP’s UC GPA is 3.1 according to her post, so most likely the UW is below 3.0. I believe she will have a hard time trying to gain an acceptance at the midtier UC’s even with that outstanding SAT score. Much will depend upon the reasons for the low grades and the strength of the essays. Anything is possible but not highly probable. She will not know unless she tries but needs solid backups to avoid being shut out.
