    I'm pretty sure that was right, if not very similar (69/2 I definitely recognise)

    No, it was negative, my calculator gave me a negative number like -25 to -35, and my answer was/similar to yours, yay!

    im pretty sure 9/2ln3<69/2 => it should be a negative number anyway you had to leave it in its exact form

    Anyone know if the UMS needed for an A* needs to be 90% in C3 and separately 90% in C4 or can it be a combined total of the two?

    I sometimes forgot to cross out my incorrect working and leave it in there as well as the correct answer, will they deduct marks for wrong working even if I did the correct working later on? And on the last question I intergrated both correctly but didn't have time to put it in an equation and calculate c. How many marks do you think I'll get?
