Can I get in?

Apparently not, it seems I'm her first.

All jokes aside, I've struggled finding the answer to my question online or even through conversation with a number of different universities.

I left sixth form after my first year, having gained 3 AS Levels. A, Chemistry, A, Gov and Politics, B, History. Joined the military, but an unfortunate string of events occurred some while after I completed my training, most significantly of which being medical, which led to me having to leave the service. In the months since then I've earnt a fair bit of money and have also gotten about half way through a personal training course, but am trying to work out what I want in the future, and if going to university to study a degree in the region of Sports Science, Health and Fitness, Nutrition etc. could be a part of that.

Would it be possible and likely that I would be accepted for university, perhaps on a Foundation course? Whilst I understand I don't meet the traditional entry requirements, the grades I do have, including GCSE's, are better than average, along with a lot more life experience and skills than most other candidates, and prior relevant learning and actual work experience in the sector I would be studying (personal training).

If Yes, how do I go about showing universities this. I don't know much about the application process, but I worry just applying through the regular system is going to disadvantage me as I don't have much opportunity to actually explain my situation and my experience, that my grades, or lack thereof, will see me ignored amongst what I imagine is quite a robotic and dismissive system that is in place to review applications.

And yes, I am aware of the options to finish my A-Levels or complete an Access course at college, but I want to know if I could get to uni with what I've already got.

Many thanks for any and all help.
