1. his voice sounds terrible. he looks like arguing other than teaching. the attitude is intolerable.
2. ppl there are noisy. 25 ppl in a class, 15 of them r playing on their own how can i concentrate
3. he likes examples that show he's different from traditional teachers. this is totally a waste of time. he makes a lot of comparison bet'n his teaching and those done by our sch teachers but i really doubt the credibility of such examples.
