Hi to all of you. so sorry that the school had to be closed at this stage where all of us are so eager to finish the syllabus.T thought it was a good opportunity for us to hold some extra classes to finish the syllabus. On 2nd thought, it may not be safe, esp for you all. so i quikly thought of this idea of sending you some message here.
I had actually prepared some kind of work sheet on 'Modern Medicine' to be printed for you. but the announcement came so unexpected that i didn't even have the time to print it. Anyway, i give you my e-mail, siowly87e@gmail.com. just drop me a mail and i shall send the work sheet over, so that you can make use of this 'holiday' to read up the text book on your own on this section on Chapter 5. Then fill in the blanks and remember the points. I think most of you should have no problem with this work sheet.
I will check my mail everyday. and shall send more work sheets over.
Please print out the work sheets for those friends who don't have internet access.
Hope you can really make full use of this 'holiday' to prepare for your exam. take good care of your health and all the best. love you all.
See you in school!
