i'm currently attending Roy Goh's class. I don't like Roy Goh's attitute towards teaching. He is simply irresponsible i could say. I took F2 in SAA and thus used to some method in solving some questions. he taught a totally different method which doesn't fit into the definition and totally doesn't make sense to me. so, i carried on my own method taught in SAA and asked him whether it is correct. he said "yes yes, ur answer is correct, but why is ur answer different from mine huh?" I AM VERY SURE MY ANSWER AND METHOD IS CORRECT. He said my method is correct too. there could only be one reason- his method is wrong. and it totally doesn't make sense to me. He simply said "aiya, just accept my method la.." and he walked off - without trying to providing further help.
it happened to my other friend as well. He said "i really donnoe. just do the normal way."
I really wondered. Is he really a lecturer?
