Oskar is a great instructor! Really helpful and nothing is too much for him. I only studied ATPL ground school at ASW, but for £3,600 for the full 6 months, the residential course is a bargain. Class sizes were small with only 6 students per intake (Which I believe has changed now to a bigger number now) The facilities are (or were basic) at the time of studying, however, it was a good experience all round.
