O levels (Chemistry) high scoring skills

Ok, regarding chemistry, we'll start from scratch, the basics, and you have to learn them, side by side, because these concepts have to be strong, since they will link to all the rest of the topics, first thing. Second thing, is that ask questions, wherever you find yourself stuck. Clear your concepts at the spot. And in chemistry, always ask the question, 'why?' In a CIE, they ask you simple questions, with why, and students do not answer them correctly, examiner reports suggest that. Always focus on why. And what more, you have to include scientific vocabulary in your answers, those used by the book, or by your teacher, since they have reserved marks for that. For instance, they ask you, metals are good conductors of heat and electricity. why? and you answer, because metals have free electrons. You'll get 1/2. You should have used the words 'mobile' or 'delocalised', to get 2/2. These are very simple things that you need to keep in mind. Okay, then he asks you, why delocalised? here he is asking you the chemistry behind it. Students get confused when 'why' comes. Thats the whole point. When your teacher tells you a concept, ask why. how is it like that. Question. It helps a lot. You learn by asking. We will go through these concepts that i just touched, when we do metals, so dont fret. For the time being just remember, that you have to be focused, thoughout.  And ask as much as you can. There are some things you have to learn by heart, i'll tell you that, side by side.  
We'll begin with Kinetic Particle theory. Its cake. :D
