I am in your shoes, only 4 months further down the road.
I went Bristol distance learning because
(a) Its cheaper
(b) Its a more effective way to learn for me but only because I study well on my own (you will require *massive* self discipline). Furthermore full time courses mean you travel at a speed consistent with the slowest person in the class.
(c) Bristol are very very good - I got over 90% average in Module 1 with 8/8 passes - Module 2 on the way.
The only downside is that Oxford only push students from their integrated course. But I think CTC do send their students to Bristol. I believe these are the 2 best places to guarantee a job afterwards - if you meet the age requirements (<27) and pass the interview.
After 4 months I am no more enlightened where to finish my flying training.... the Oxford brand, or the Bristol skill/people/cost?
