You have to show full working out. Even for some 1 marker questions like the limits type ones, you have to show how you got your answer (some markers are harsh). Despite some answers naturally coming to head because of the easiness, you have to show working out because specific steps are given...
For question 9 i put A, but i can't seem to find the answer for q9 but i'm like 90% sure I am wrong.
What's the answer for 9?
I will do the rest of the paper next Wednesday after 4u, and i shall tell you about the written part of the paper :D

Yeah i forgot lol, when you get the x value, sub it into the original y equation to get the y coordinate. Hence (-2,11). Im not sure what you mean by f'(x)>0, what do you want to know?
True but also make sure the volume is of appropriateness. I.e (5mL of ethanol and 5ml of ethanoic acid were added, not 10000L of ethanol)
hahaha so much exaggeration in that last volume, just make sure volume is appropriate.
