The Instructors work to the sylibuss and standards required by the CAA, this is the same at Hurn as it is at ASTAC or BAe Cwmbran.
What differs is the attitude to hard work and comittment of the students, at the varying colleges.
At Hurn, there are NATS cadets who have undergone a selection process and have gained their place on that process.
At ASTAC and Cwmbran, the students have been forwarded by their employer or, exceptionally have self sponsered, and have undergone much the same selection tests to get on the courses.
Ultimately, where ever you are, you will get maximum support from the Instructors, but if your attitude smells like crap - you'll be treated like crap!
As an operational ATCO I've seen both sides and although I would give students as much leeway as possible, some of them have breathtaking arrogance and expectations.
I would venture to suggest that at Hurn, whilst the majority are commited to passing the courses, they haven't given up all and everything to attend a course that makes the difference between ultimate success, or failure and penury.
If you want to succeed, not just at the college but at subsequent unit standard, it's down to to positive attitude, ability and commitment.
