@WoWMaster: The UC’s do not ask for Senior grades for admission purposes since applications are due November 30th. If you are asked for a supplemental, then you submit your first semester senior grades.
For the UC’s, Freshman year grades are reviewed to make sure that you pass the a-g course requirements.
Sophomore and Junior grades will get you into the UC’s and Senior year grades will keep in at the UC’s.
You are required to maintain a 3.0 weighted UC GPA with no D’s or F’s Senior year to keep your acceptance. An Unweighted 3.0 UC GPA is required for UCLA and UCB and no more than 2 C’s, so Senior year grades may not be too helpful.
