10. ah great, for question 2 instead of differentiating -3xy I differentiated 3xy which is why I couldnt work out b, cos of one silly mistake I've lost 10 marks or will I get a few method marks?
12. 50/75 ? C?
13. How many marks lost for getting 32(In2)^2 +32In2 - 12
14. 65/75 enough for 85ish UMS? thoughts?

No your are absolutely correct. good spot. It won't affect the answer for part B though
16. If you got an answer wrong on part a and used it for part b, do you still get method marks on part b?
