Cabair Bournemouth....great instructors, great structure and great results to go with it. A couple of small niggles here and there but nothing my healthy 95% average won't help me forget. I've put the school average result for the last two sittings below....
September = 91.2%
November = 93.6%
...results don't lie.
If I were you I would go visit a few of them, speak to some past and present students, compare prices and see who you like the look of at the end of it.
Good luck!
