Applied to uni too earlyWatch
You should be fine, some students will get their applications in by mid october as that's when the deadline is for certain courses / other universities like oxbridge. Early submittal won't disadvantage you, and some universities send out offers early before the january deadline, so you might have some before christmas if your apllication is good.
It doesn't matter when you apply before the deadline, as all applications received before the UCAS deadline (15th of October for Medicine/Dentistry/Vet Med or Oxbridge, 15th of January for everything else) must be considered equally by the universities receiving them. It will neither advantage nor disadvantage you in terms of admissions. It is one less thing for you to think about during this academic year though so you can just now focus on your studies without worrying about writing personal statements and suchlike.
