If you're aiming high, you don't go a tutor that teaches 50+ people (ie. jack)
get a private tutor.
Don't forget his tutoring is 'come whenever'; there is no signing up and a set amount of students to teach - this is why many other tutors differ from him.
He just cannot teach higher up techniques to people that he's only seen for one lesson and have no clue what their capabilities and potentials are, if you needed more help you simply ask him before/after a lesson and he will gladly help.
This is why many people go to his tutoring, when they are in doubt they can come to him expecting a reiteration of the course and not getting confused and hence he is successful.
I'm not gonna post any more cos this topic is redundant, he's a good tutor, not the best, but his pay-rate says all.
If you don't want to go to his tutoring, then don't.
But don't put down his tutoring methods simply cos it doesn't cater for you.
case in point - go there if you want to know what is tutoring is like. People's opinions (including mine) is completely subjective.
