You asked at the wrong time, everyone got their grades today
1)....the best bars and clubs - depends on what you like, there is a lot of variety, pretty much just go where other people go in freshers week and you will find things you like, everywhere will be rammed and pretty good anyway that week, the cube is good in freshers week apart from that there is oceana, bedfor place (which is mainly like bars with dance floors) and then portswood which has loads of cheaper places, jesters is a bit renound for being really cheap and really nasty but at the same time soo good
2)....best campus - you dont get to choose your campus, it depends on what degree you are doing, you will be based at highfield campus. arts degrees like languages, archeology, history etc are based at avenue campus and geology, oceanography and marine biology are based at the NOC.
3)....what its like to live there and if having a bike as transport is enough - bike is defo enough, probably not needed though, if your in halls in first year, which i would trongly suggest, then you get a free bus pass
