THe point is that he doesn't teach you anything. All he does is give you paper after paper to do. He won't teach you the concepts, or what's required in the answer. My cousin was coming home with answers to questions saying "answer in full-sentence" starting with the word "Because...."
He "teaches" the english and maths himself. There is no writing or general ability. But the acceptance tests' standards are very high, and thus most are able to get into selective anyway. I think many of his students also go to another coaching college (this was the case with my cousin's class)
I am currently going to Mr Ye's classes STTC and WEMG so I know how it is. For STTC, We come in, chat and talk, then Mr Ye comes and gives us our tests. We have 3 subjects. Maths, English and GA. I must admit though, Mr Ye's English isn't really that good and some questions are incorrectly worded but you can't blame him, he isn't from an English backgrouand.
The test must be done very quickly, like in the selective test. This is great training for the real test once it comes. After finishing the test, we have a short 10 minute break before marking each other's work, then we copy our incorrect questions down fo review at home. After all this, Mr Ye explains all the 'tricky' questions for half an hour.
In WEMG, we have multiple rounds. Speeding, where we do 25 simple maths questions in a minute and a half, spelling, where we get tested on 10 words, English, where we receive our homework booklets and do some English, then the last round, GA. Before English, we have a 20 minute writing lesson learning a new type of writing each week. Mr Ye has really helped me. In Year 3 I was an average student. Strangely, I passed the entry test which wasn't that hard and gradually I improved until now I am the top in my school in English and math s and GA and writing.
