There's a C4 thread so might as well create a C3 one :P.

Has anyone started any revision yet??

We have finished M2 and are onto the last chapter of C3 so you're not the only one who hasn't finished.

How do you find the range of a function? Hate functions :'( is it by plugging in the x-values?
even though it's one of the easiest chapters in c3. Don't think I'm gonna do to well in jan.

Range if you are asked to find the range for example in inverse in f-1(x) you look at the domain i imagine right guys? and if you are given a graph you find where the line stops , you look at the y axis

Doing C3 and D1 in jan. Only thing that really troubles me is trig but I have quite a bit of time to get it right. Need an A* for UCL so I better start working soon, anyone else going for an A*?
