4 subjects seem only a little to those SPM students, but the number of chapters for each subject is about 2 times more than that of the corresponding SPM subject! For instance, you have a total of 14 chapters for your SPM chemistry syllabus; I have 31 chapters for mine! Even worse, each chapter still has so many concepts that need to be learnt and understood. In organic chemistry, for an organic compound like alcohol, I have to remember a lot of reactions that it can undergo, and also the reagents and conditions that are required to make the alcohol undergo a certain reaction. For example:
Reactions of alcohol with PCl3, PCl5 and SOCl2:
r.t.
3CH3CH2OH + PCl3 -------> 3CH3CH2Cl + H3PO3
r.t.
CH3CH2OH + PCl5 -------> CH3CH2Cl + POCl3 + HCl
r.t.
CH3CH2OH + SOCl2 --------> CH3CH2Cl + SO4 +HCl
This part of reactions is just 1/4 the reactions of alcohols that I need to know and remember. From the reactions shown above, I still have to know that the 2nd and 3rd reactions are the ways to determine the presence of -OH group because of the liberation of the HCl gas.
I am glad that when I was writing this blog, I did not refer to my notes but I still could write out the reactions of alcohols. All these really need extremely hard work to remember and understand. But the STPM chemistry syllabus is really a huge and heavy burden and so the syllabi for the other subjects.
I really wonder how the people out there could get 4 As in STPM? How can they remember all the things in such a thick "telephone book"? Sorry, not one, but 4 "telephone books"!
