Hi there!
So first of all, I'd like to reiterate Slowlorisincognito's point of not signing any contracts for housing until you're sure about your future with the university. The contracts are worded really carefully and it's such a pain to get someone else to take your place and get your deposit back - speaking from experience.
Secondly, which course are you doing and at what university - if you don't mind me asking? It might be better for you if you have a chat with your course leader as they will be understanding and work objectively with you due to the amount of money you're paying. Also, it might be worth seeing what student support you have available and talk to them now in the first couple of weeks of semester two.
It would very much be worth taking semester two, if only to get a Certificate of HE (this is when you've just completed the first year) as it'll show any other universities that you've completed the first year, should you apply to another one.
Could it be worth taking a gap year in between year one and two? It may give you some time to think and get advice and maybe even do an internship or two in the area that you want to go into? Just to make sure?
It's quite normal to not enjoy the first year of university as most of the modules aren't choice-based. Have you looked at your course map for year 2 - might they be more to your taste?
I too tried to skip reading whenever I could as it didn't interest me.
So, to take some things away from this post:
1. Talk to student support / your course leader / your academic tutor
2. Consider the second year modules, will they be better?
3. Don't sign any housing contracts
Keep us updated with what's happening please!
