This Article is for those students whom are asking about how to do better in "O" levels Chemistry. I hope to share some insight on what you can do to improve on your Chem.
One important key that all Chem students must know is that, this is a subject whereby you need to build a strong foundation before moving up to the next level. It is a subject whereby the earlier topics are more important as the latter subjects. Without the basics, you would definitely have difficulties. DEFINITELY.
So, it is of the utmost importance that you must review your notes and textbooks of Chem for Chapter 1 - Chap 8 (up until Atomic Structure, Electrons, charges, Reactivity series and why certain element are more reactive/less reactive, Periodic table arrangement, etc).
Now, while this may sound like a lot of work. BUT, once this portion is done, the rest of the chapters will become soooo much easier. So, it is definitely worth your investment of time and effort.
Now, why is it that Chap 1-8 is important? Let me give you an example.
In the latter chapter of Ionic bonding and Covalent bonding, what is it actually talking about? It is talking about the reactivity of the metals and non metals, and how they will bond together. BUT, if you chunk down further, it is testing more of your understanding of the periodic table arrangement and electrons . It is because of the lack or additional number of electrons which causes the instability, which explains the reactivity level (Cation / Anion).
(Just an interesting note for you, reactivity can be equated to the insecurity of human beings. The more things (in Chem, it will be electrons) that a human (elements, metals or non-metals) is missing, the more this human wants to bond (either sharing or taking of electrons) with others. But if this human has extra, then, this human will only feel secure through giving aways or share with others all the extra things. See if this helps you to understand Bonding better.)
So, imagine if you don't even know how the periodic table is arranged, what electrons are, what is missing, whether is it a metal or non-metal, do you think you can answer the questions properly? Obviously no.
Another example would be Oxidation and Reduction. One was of seeing whether it is Oxi or Red is whether there is loss or gain of electrons. So, what is the basic topic of this chapter again? Back to Chapter 1-8 again. If you don't understand the electrons, and how to identify, you would definitely face challenges.
To score an A for O Levels Chemistry, is very easy, and you just need to do your work on a daily basis. Take the next 8 days, focus on doing well in your basics, in the first 8 chapters (or up until Atomic structure, depending on which text you are using). Upon completion of this part, you can be sure of easier path ahead in your studying of Chem.
Now, if you are keen to know how you can guarantee an A for your Chem, drop me a message here.
