Private candidate! Please help!

I want to re do AS Maths, after failing this year. If i become a private candidate, will I need to pay for each module (C1, C2 and S1), or will i just pay for the Maths as a whole. Also as i private candidate, will i get the opportunity to do the AS maths this year and the A2 maths next year, or will i need to do them both at the same time?

As a private candidate you can do what you want. So you can do them together or separately as you wish.

You need to pay for all exams you take.
