Social,
How right you are.
Common practice around here is to take private theory/technique lessons with a teacher who is supposed to prepare you for an exam in either ISTD or CDTA (Canadian).
Our own coach who is also an ISTD Examiner offers an intensive 2 week 4 hour a day preparation session aimed at not only regurgitating the books but also to prepare you on the theory of movement and what the examiners look for.
My wife thought it all a bit expensive until I pointed out that at what she could charge as an Associate would pay his fee in 20 private lessons.
