    my maths teacher told me that you have to get 90 ums in both c3 and c4 to get an a* (along with 480 ums total)
    What I've said above is 100% correct, and 90/90 is a case of that. There is no requirement to get above 90 in both modules, as long as you get 180 or more in total. If you're not convinced - my results are below:

    my C3 grade was 100 and C4 was 84, and I was awarded an A* with this combination.

    I have some model solutions for the C4 questions only, done by my teacher if you want to check the final answer and a possible way of solving.

    Marccs Might be of some help.

    Hey, does anyone have a compiled list of formulas / proofs (that aren't in the formula booklet) that we need to know for the exam. Much appreciated.

    20ln(h) is the same as 10(2ln(h)). 2ln(h) is ln(h^2) so it's 10ln(h^2). Then combine with the other log with the addition rule.

    Well the C3 questions on the C34 paper were more or less identical to the C3 questions in the normal paper, so it wouldn't hurt to know how to do them.

Size:  39.3 KB I set up a differential equation in dh/dt and separated the variables to find the value of h at t = 8 and then subbed it into my equation for dh/dt. This gave me the correct answer, but I don't really get how the mark scheme has done it?

    Well instead of using the value of t they've simply used the value of V at that time which is easily found as the rate of change of volume is constant
