I like Lincoln.. Im from Lincolnshire so you know.. Haha, but erm I heard that Bishop Grosseteste isn't very good but then others have said it is although mostly it's down to personal preferance but I know people who underachieved to have gone here and chose this uni as their last choice just incase they didn't get great marks. Try the original Lincoln Uni, that is better. Hope this helps!
Btw. atmosphere: Lincoln is fun, there's always something to do and is a great place for shopping- anything really!
