Is it over for me? (Methods)

I have been doing pretty decent on my exam one practice and I felt good going in today but I choked and probably got 12-14/40

I know all the content and how to solve the questions it’s just methods AINT my bread and butter it’s my 5th and I’ve always struggled with it. I’m quite good with the calculator and have done a few exam 2’s, and will have a good bound reference.

With let’s say a D unit 3 and C-C+ for unit 4 and probably a D-C in exam 1 how many marks out of 80 do I need for tomorrow?
