was at oxford doing the modular ground school from 20th oct 2003 - july 2004 - was excellent and passed 13 out of the 14 exams 1st time - just missed one by 3%.
ground instructors were excellent but alot of them have moved to the new school that has been mentioned here before.
big hint is to go somewhere where the feedback question bank is ample and where you are treated as a customer not a school kid.
there is also alot of banter between modular/app at oxford so be prepared.
hope u pass them all.
happy landings
