...
I got an offer from Bristol for English this year. I'm a year 14/resitter, and I didn't get an offer from Bristol
last year.
OP - don't make any decisions
now. Carry on with your application and your studies this year
anyway - you can email the universities and ask for deferred entry at any time, if you really don't want to go next year - that way if you meet your offers this summer then you don't have to worry about UCAS again next year.
College can be fun - it makes sure you're getting out of the house, meeting people, and it keeps your academic skills sharp. Plus, I've really enjoyed the chance just to pick a subject I haven't studied before and learn about it for a year (for me, Philosophy). Being a proper member of a sixth-form college has also made UCAS and resitting so, so, so much easier to arrange.
And don't listen to people who tell you you won't get any offers if you take a year out/have to resit - they don't know what they're talking about. I've a friend at college this year who reapplied to Cambridge after missing her offer and has been accepted again. Anyway, you really
won't have any problems at all if you just work HARD this year, get your grades, and use next year to take a course that look interesting just for the fun of it.
Anyway - you don't have to spend ages trying to justify to the unis
what you're doing with your year, whether you decide to study, work, or go skydiving in Thailand. I only mentioned, in passing, in my PS that I'm taking a course in creative writing and that I'm studying an EPQ and an A-level in Philosophy. As long as you're still motivated, still passionate, and still excited about your degree, you're good.
I don't know what subject you want to take at uni, but if you want to ask questions to people who are, or have been, back at college for another year to resit and reapply, just pop in and say 'hi' here:

But good luck, with whatever you decide. You'll be fine!
