Thank you very much for your kind reply. It is clear to me now.
This is the first time I know about Opentuition and I find the class notes is very useful to me. All the subject matters are very understandable in this notes. I really appreciate it.

I do hope I can get a better result this time by the knowledge I gain from the notes. Once again, thank you very much.
