I also went to Oxford and graduated in 2000.
I had a really good time but it is a tough course. It has changed a little now with extra twin hours and fewer single hours.
Personally I think it is a better course as the extra twin hours will ensure a better first time pass on your IR and that is very important when looking for a job. The instructors at Oxford were very good and the school does have a good reputation. However, they are there to make money and will try and screw you if they can.
Good luck!
