Worried I'm not interested in university anymore academics isn't for me?

I don't know what to do I feel like I keep failing all the time.
So all through school I achieved average grades even in my final year even when I worked very hard. My results weren't the best and I failed maths . I repeated these exams the next year I passed but still I didn't achieve what I was capable of even with the hard work I put in and I passed maths. Made it on to a IT / Business course. I wasn't quite sure what I wanted to do but it seemed like a good course. I passed first semester the second semester I had two modules which were maths based . I failed both I need to repeat them I can't bring myself to repeat I'm sick of failing. And next semester there is programming and engineering which I could possibly fail. I just don't know what to do I just keep failing. There is no other course I would do in university either. I used to think this was the course for me. I only did it because everyone kept telling me this is what I should do and I had no idea what else I wanted to do. I felt it all through school and family you are expected to go to university in order to succeed in life. I don't feel I'm academic minded .

I have realised I've always loved swimming ever since I was young and learnt by watching someone and got many lessons always enjoyed it. My family always said I was a strong swimmer even though I think I'm not fast. I never did competitive swimming as I didn't have the money and had a slight fear of deep water but I've changed. Now I'm thinking maybe I could take up masters competitive swimming and become a swim assistant coach before becoming a instructor ans life saving course as well. So I would be qualified for both a life guard and a swimming instructor Otherwise I'm completely stuck I'm just worried I'll hate it as i am slightly a quiet person but I can be confident at times.

I don't have a personal tutor in my university I don't know who'd I'd speak to.
Also I need to make a decision by 28th June if I want to repeat my exams.

Well I definitely don't think that there is any benefit in repeating your exams; if you are going to stay on at uni, it seems that you would have a much better chance, and much more fun, if you pick a new course and start again in first year.

I don't know much about swimming, so I'll stick to the university route. Is there definitely no other course that you want to do? Are their any particular topics that you find yourself drawn to reading about on the internet or discussing with people? Perhaps there is something that you would be happy to do that you had never really considered, due to the pressure to do a maths based degree. If you can get through a degree without being too miserable (happiness is the most important thing), you would have options other than swimming, and, depending on your uni, you could train with the university swimming team.

Finally, don't let the supposed prestige around the academic route affect your decision. It's held in high regard in certain places (TSR), but there are plenty of people, and jobs, who/which don't think in that way.
