To me he is an excellent teacher with a unique approach to teaching, a great fun personality, who speaks clearly and anyone can understand, who keeps you engaged in the lessons etc... He's one of my favorite teachers on here. To the ppl making these rude dumb comments about him, I can certainly say, you really haven't met anyone weird, crazy or scary in your entire life!
