Year 13 Mock Results - Feel Awful

My results were:

Applied Science - Distinction (Mock result)

Psychology - A

Biology - E

I'm really deflated at the Biology grade, having usually getting Cs and Bs and doing exam practice and going over notes. I don't know what to do, the Universities I want to go too require a B, C worst-case scenario. Is there any hope? Any time?

I had Applied Science exams going on too for Unit 1 and 3 so I was focusing more on those as those would be going towards my final grade, regardless I feel really depressed and hopeless
