I'm not allowed over, What?

I got my grades back. Well only one grade back. My motor Development teacher hadn't graded our tests yet. I did get my grade back on my Biomechanics test. I think i did ok considering it involves physics, and trigonometry and i've had neither. I spent so much time studying how to do the problems I got 24 out of 30 points on that! So I must've not done my best on the multiple choice. I did PASS (with a 74), However I did not make the B that I wanted. After telling Will he was not inpressed that I passed. He thinks highly of school and knows I can do better. Apparently I am not allowed over again until I get my grades up! Can you believe it?
