There have been a lot of arguments for and against my point of view. But speaking as someone without a degree (and embarking on a modular training course, but that is and an aside). My advice would be to get a good science or maths based honours degree (2.1 or above) before you really commit to pilot training. There is as good a chance that aviation is in for a rough ride as there is that it is not. When you have a good academic background you have flexibility.
However, you do not need a degree to become a pilot, and the theory stuff would barely test your GCSE knowledge! But overall, taking things into account, weighing up the options, creating opportunity and not painting yourself into a corner are paramount considerations for the years to come!
Might not have been the answer you were looking for, but I believe anything else would be nothing more than a venture and not a plan. Neither would skipping Uni provide a discernable advantage at the end of it all.
I wish you the best of luck
