I've just comprehensively disproved the theory that frequent lessons are better, during my second lesson in two days.
That's true for some people. I've always done appallingly badly on intensive courses. I need time to think digest, read, recover, recuperate, plan etc etc.
As for pulling wrong knobs, make a rule that before you pull or push anything you'll have a look and confirm out loud what it is. Very necessary in the future when you fly different types that inconveniently change knobs and swap around their positions too.
