UEA is a very good university for Business related courses and is actually highly regarded by alot of people.
There is more to picking a uni. However, have you thought about spending the next 3/ 4 years in Norwich? Now there's nothing wrong with it, but I have to say the Halls remind me of a prison. Now i've not got much experience of the place, but there are other places that offer similar courses.
Take NTU for example. Nottingham Trent do a BIS course and you only have to get 240 points. Not only will you get a gooooood degree but you'll have the time of your life if you like ladies, clubbing and having a laugh with ya mates.
