I took a 1hr tutoring with . I must say he explained pretty much what I needed (basics of states, modes, controller, etc) and some issues with looping. I am expecting to have another tutoring pretty much soon with him again (he knows his stuff). He is also quite flexible, I made a mistake while paying via paypal, and he took it quite well (he would receive the payment in 3days xD). Anyways, Ive also been asking him few questions via skype, and he was quite friendly answering them aswell
I do recommend him.
