Look you don't need to club, dont need to drink dont need to do all that to fit in at university, youll find likeminded people on your couse or throughout the year. Freshers well for me was just when everyone is super sociable and really trying to make friends. about your timetable, what I did first year was just follow the crowd find someone on your course and and talk to them see where there going. I have friends who don't drink alochol, trust me youll survive without it and to be honest your better of without it.
