I wrote the answers to all my questions on the exam so i could take them out and my teacher could mark them. some of them I got wrong, my teacher said I got about 95/100 so I tried to remember the actual answers to the ones I got wrong.

I only wrote the final answers, not the working out. Also, I haven't included the drawings and graphs.

EDIT: There are mistakes here, will fix them soon.
