Maths exam : Terrible

Oh my! I just got home and checked my notes...most of my ans are wrong! Die! I will be very glad if I can get D+ for maths. I know how I fare in this maths paper, and hence don't dare to ask for much, just a grade D+ will be very kind to me. Please, hope I can get a D+ for it. Please don't dabao..

Now worried like hell, after discovering that 90% of my ans are wrong!!!!!!!!!
