In general, it is very good - it was in the top third of the the top 100 universities league tables. It may have changed since I was there 1998-2001 though. Anyone going, I would recommend you try getting into Wantage Hall. It is without a doubt the best hall with the best atmosphere and there is going to be an absolutely top notch 100th anniversary formal dinner, this year being the 100th anniversary of the hall's existence. I went to the 90th anniversary dinner, and that was fairly top in itself. Names of everyone attending go on the walls of the dining hall staircase.
