Should be an A* assuming your other modules can make it up to 480 over the six modules.

friends, for q 3b, i worked out gradient right and everything and set it to 0 then stupidly got -66-3pie/22+pie as my answer, how many marks would i get from 4?
I got minus too
4. hey, how many marks would I lose on question 3 if I did not put dy/dx after I differentiated the cos pi? I differentiated all the rest correctly, but this meant I also would have got part b wrong as well?

6. Hey, can anyone say what 67/75 and C3 and 67-70/75 in C4 would probably be as a grade? If my other UMS adds up to 480 will that be an A* or an A?

For 7.b,can you do y=8 minus the equation of the curve instead? Limits 0 to 17.5?

No

The integration method would have looked like this

Since the limits differ, a single integral solution can not be performed.
