Lister is quite correct in that cheapest isn't always best. There may be valid reasons for a school to have lower running costs based on location but you will also have to factor in travel time and fuel in your car.
I was at Glasgow earlier this week as a passenger. A good sized airport and one that would be fun to learn at. I started my training at a major airport in controlled airspace and don't regret doing so at all. It gave me great confidence when taxying around the big jets, sharing the R/T airwaves with the commercial crews, following ATC directives regarding airspace restrictions etc. etc.
Get your exams out of the way asap and then concentrate on flying. You can always get back to the books to brush up on, for instance, navigation. I believe Mazzy is correct in the time limits - but your school will be able to put you right.
Mazzy - if it is taking people 3 or 4 days to read this thread you really must start taking the book option seriously ;-)
Still no documentation from the CAA - although they did debit my credit card in record time - at least I know the registered mail delivery worked...
