    Pretty much the same stuff every year, go through all the past papers and make sure you can answer everything.

    Does anyone know what formulas we need?
    Especially for area of shapes. Lol.
    I'm struggling with the basic questions because I know the formulas.

    does anyone have a list of all the extra formulae we need to learn for C2 that isn't in the formulae book. for example the surface area of a cylinder or volume of a cylinder, as that often comes up and it would be nice to have a list of stuff like that to make sure i learn it. Thanks

    Dunno if there's anything missing, but I'm pretty sure it's all we need to know: http://imgur.com/D24Qb5W FYI we can use the C1 formulae which have the area stuff I believe.

    Have you tried the bronze, silver and gold papers for C2? They are really helpful.

    Have you done all of the Solomon papers? Have you gone thorough the mixed exercises in the C2 book, Have you done the books review papers? Have you looked at any of the questions that you got wrong in the past papers you have done and re attempted them or looked at a video solution of how to do them?


    Also regarding your comment earlier about revision formulae, all you need to do is write down the trig rules, radians rules (r x theta etc.) Look through all the different types shapes that you can get asked to find the surface area of etc..


    Hope this helps

    I am struggling with parts of C2, especially with the differentiation parts and finding the maximum and minimum points etc., can anyone tell me how they remember how to do this? I have no idea :confused:
    Well you differentiate the function. Make the differential equal to 0 as a turning point has a gradient of 0, and find out your x coordinate
    To find out whether it is a maximum or minimum, differentiate the differential
    Sub in your x value and if it is greater than 0 it is a minimum and if it is less than 0 it's a maximum
    and to find your y value, just sub in x to f(x)
    If you're asking how to remember well just remember that method
    And specifically for remembering when it's a max or min
    If it's less than 0 it means it has to be a maximum as nothing can go over 0 vice versa
    (This is for my revision btw that's why I typed out the whole method)
