Need help making an a level decision!!!

I am currently studying 4 AS levels, including Maths. I am desperate to study and complete A-level further maths. I know that I have the ability and passion for maths to attain a good grade.I don’t have much time to start many new modules as the exams are not far away.
If I were to pick up FP1, would I receive a prediction for A2 level further maths? Would the unis that I apply to see that I have as level further maths?? And that I intend to complete it at A2 level?

That would mean that this year I would be doing C1, C2, FP1, S1
I would then like to study Maths, Further maths and economics at A2.

This would mean that I would have two units for economics, and the
following for maths and further maths.

C3, C4, FP2, S2, S3, M1, M2.

All together I would have 9 exams in June 2015. Is this manageable??
