Registration fees for A levels as private candidate?

[CrossboneSRB]

All right, I'm planning to sit A level exams this January, I've been persistently studying the subjects but I'm not sure what the fees are. I'm applying rather late because I've found out where I can sit the exams by coincidence when I was losing hope of ever finding any information on the subject, so apparently I have 8 days to register normally I believe.
Anyway, I'm in UK and I'm planning to sit Edexcel A level Maths, Physics and Biology, I won't be able to pay for everything in bulk at one time and therefore I need to know the costs of these exams I would have to pay this month, how much are the registration fees, the exam fees and any other costs that come before January, I already have the books so at least that's out of the way.

I this FAQ on the Edexcel website that I hope can help you out and also this discussion on The Student Room which could be informative.

Good luck :)
