Will UCR rescind me if I got a D first semester for AP Calc BC but I’m headed for a B- for second semester?
Possibly, better call them and talk to your guidance counselor. Better to find out now than later.
Talk to your guidance counselor before you call. Find out how your final transcript will be presented to the school (ex. does it have final grades only? or semester grades?) so you know exactly what the school will see. If you can get the final grade to a C you could be ok.
