Dear 0903 PM10,

I heard that some of you are facing some difficulties while doing the tutorial, don’t worry, don’t press the panic button. The purpose of giving you those questions are to allow you to learn chapter 3 through questions. You might not be able to find all the answers to the questions by just referring to my notes, you have to do some extra research on your own or maybe some thinking while doing those questions. Remember I have taught you guys on chapter 3 so use the knowledge and get involve in some analyzing and critical thinking and I believe you will be able to answer my questions. If all fail just show me that you have at least try to attempt those questions (Show me your effort). We are going to discuss the tutorial this coming Tuesday.

* Reminder: Class resumes this Tuesday (21/04/2009)
** Class test on: Chapter 1, 2 and 3(everything that I have taught you). 5 structured questions and 10 objective questions. Answer all in question paper. Duration: 1 hour.
Expected on 23/04/09.

Happy studying!


Regards,

Mr. Lucas Chan

Ps: So prepare for the test probably on thurs
