Do Universities care about what you do between Further Education and Uni?

You may well be questioned about it, but if you give good, intelligent reasons (not just 'I didn't know what else to do/I didn't want to go into full time work yet') then there shouldn't be an issue. If you have a real desire to do something, it should come through in your PS and your interview. They won't immediately throw your application away because you've done a mix of different things.

They may ask why you've changed your mind (from the A level subjects to sport to the new A levels and scriptwriting).

why are you still doing your BTEC if you want to do the scriptwriting degree? You'd probably be better off working part/full time now (you definitely don't need a sport BTEC to get a job in a leisure centre or as a lifeguard or anything), doing your gym course alongside that if you want to, then starting your new A levels next year.

Well I guess a spell in the slammer for sexual assault wouldnt go down well........

Yeah I'd have to put thought into my explanation during and after I send out my applications on UCAS, it was really a big rush to find a course that I could settle with (at the time I thought Sport Science was the only thing I wanted to do), but after sitting down and contemplating I decided it wasn't necessarily just that.

Scriptwriting/Journalism and Producing are my big interests, then it's Exercise Physiology/Nutrition. Since my favorite one of the two is a highly risky career route I feel I need this BTEC. Not just as a back-up qualifcation but because I really am a freak about exercise physiolog, nutrition, human anatomy and all that shizz.

Oh right I see - it's really great to study anything you're interested in
Well if you're just interested in it, you could maybe do a 1 year btec or something? Obviously depends how long you want to study for, but would the new A levels be free if you start when you're over 19? There's clearly nothing wrong with learning things you're interested in, but it might look like you're just confused and keep changing your mind/think you'll be better at something else. It's much more common to do a few open uni modules/evening classes in something you're interested in rather than do a whole 2 year btec, then 2 years of a levels, then apply to uni for a degree! Open Uni especially would give you more freedom to do modules you're interested in, ie more nutrition modules etc.

If you can live at home/afford to rent whilst you study what you want then have fun learning!

OMG... I'd be 19 when I finish! I've just realized. Thanks for mentioning that lol... I wouldn't have thought about it until it was too late.

My only concern for the future is the risk involved with scriptwriting and producing. And right now, I think I want to start the A-Levels by 18 while it's still free :/ I guess I should just do half of the BTEC and gain the personal training qual from it. Thanks for the insight on the uni opportunities as well I think I have a clearer idea, now I just have to decide when and how to tell my college lol
