HI
Currently doing atpl's with bristol. As everyone else has said, as long as your willing to work at it you do not need masses of mathematical knowledge. Basic formulae and manipulation, probably about comparable to gcse level.
Are you doing distance learning or residential. If you are doing distance learning and finding it hard you can always go for some instruction then, and if your residential the instructors will be on hand. However you should be fine.
Good Luck.
