Aye, not too many people will dissagree with that, Bristol are excellent.
You do get cheaper courses elsewhere and the brush up course of 2 weeks each module + the 1 week for exams doesnt quite suit everyone, (work commitments and the like), but if you can get the 3 weeks off then bristols by far the best way to go.
shop around though, theres a few schools (oxford, cabair,cranfield, bournmouth etc...) and you might find that the price and the course structure suits you better.
The training material with Bristol is top class and the online material is excellent. If your stuck on any concepts theres animations that help you understand.
Ive heard very good things about all the schools though, just pick what suits you mate!
