When examiners mark your work, how exactly are the points awarded? I have heard you get a mark for using the correct method of calculation, but what if this is the case, but the numbers you have used are wrong? Do you still get the mark.

you would get the method mark(s) but not the accuracy mark(s) if you use the correct method but the wrong numbers.
if you look at past papers' markschemes, on the side of the working you'll see M1 A1 or something like that.
M1 is 1 method mark & A1 is 1 accuracy mark.

so, if you get the method right, you'll get full method marks but you'll gain no accuracy marks.

(Original post by Becky68M)
With one of the questions in the M1 paper, it gave you a position vector, and you had to find an expression for the velocity, so i differentiated it once. I don't know whether i deiferentiated it right, but i just wrote ''differentiate'', i didn't give any equation for it. So, for example, say my differentiating is wrong, will i still get a mark for saing 'differentiate'?
If it was worth 1 mark, probably not.

If it was worth 2 marks, I'm sure you'd get one for knowing dx/dt = v.
