A-level advice Urgent!!!

Basically I didn't get the grades required to study economics and maths a levels (Edexcel exam board) at school so I decided to self study them I already understand that economics has been reformed and that maths is being reformed next year so my question is how are the economics exams going to work for example are there going to be AS exams still ? All the details would be good ,THANKS
Anyone in this type of situation please reply,thanks again.

Maths is not being changed until 2017 so AS maths works as now and contributes to your A level grade.

New AS qualfications don;t contribute to your A level grade.

I think two self-study A levels on top of your school subjects is too much - you don't need Economics A level to study it at uni ...

I just do BTEC ICT

It's risky - what grade did you get in Maths?

B ,additionally I wanted to ask are there not any AS resits for old subjects like economics ,physics etc that i could just pay for to sit the exam
