I would advise going in halls first year then moving out to house with your bf if you're still together for second year as other people have said on this thread.
I lived in halls last year and I did not like it at all, i dont know why...it just wasnt what i expected. all my friends came from my course and none from my halls, but i would still suggest moving into halls first year as this is not always the case. many people have made very gd friends in halls.
The halls I lived in were quite small aswell, where as this year i am starting my degree at a different uni and the halls are vast, the whole lifestyle will be different, so im hoping that i will settle well there.
Also, it is sometimes a bonus if you're halls are on the actual campus, so dont have to travel far, especially if you are intedning on working hard.
I want to move in with my bf too, but i think im gonna wait till 2nd year and get used to everything and try and make some friends.
In conclusion, I would regret not living in halls, just even to try for the experience, especially as a fresher.
Anyway whatever you decide, good luck!
