Going forward it is a good idea to do some basic research on your own before posing a question on CC. Often you can get information directly from the school which would be 100% accurate. For this question you can google “XYZ university class profile” or get the school’s common data set by googling “XYZ university common data set.”
Unsolicited advice - try to figure out why you don’t perform as well as you feel you should on “big stakes tests” (anxiety, lack of proper preparation etc.) and try to figure out how to handle things better – once you get to college you will have some classes where the grade for the class depends solely on the midterm and final and you will need to be able to demonstrate what you know on those exams.
