Dropped out of Uni but now looking to go back

I was originally doing a 3 year degree in Mathematics however I dropped out due to personal reasons as well as no longer having a passion for the subject.
I am now considering going back to university but to do a degree relating to sports as that’s my true passion.
Any advice on where to start or what to do would be greatly appreciated as I am completely lost.

How many years did you study maths for? That will impact funding if you're a UK student (and also who is likely to be the best option to approach for a UCAS reference)

Do you meet the entry requirements for the sports degrees you're interested in?

I did 2 years of my course as well as repeating the second semester of my 2nd year due to me becoming severely ill

So 3 years of previous study. 2 if you can provide evidence of compelling personal reasons for the repeat.

That means that at best you won’t have a tuition fee loan to cover fees for year 1 of a new degree (or year 1 and 2 if you can’t prove compelling personal reasons).

The previous study funding rules for part time study are much more generous. Have you looked to see if any universities offer the subject you’re interested in as a part time course?

I haven’t looked into part time courses but that does seem like the better option for me. Would applying to these types of course be done through UCAS as well?
