Half way through module 1 with BGS. Notes are excellent, and feedback on e-mailed practice exams is within 24 hours.
Obviously I can't compare them to other schools as I've only been with Bristol, however I have NO COMPLAINTS whatsoever.
Try a search as this topic comes up ever week or so, I don't recall every reading a bad word about BGS.
anyhow back to General Nav....
Best of luck with your exams.
