Chemistry resources that will be of benefit to a South African student?

m.zakariyya.g

HiMy name is Zakariyya and I am in my final year of schooling in South Africa. I am doing Physical Sciences as a subject. It consists of two papers, Physics and Chemistry. For chemistry, I desperately need more resources as I genuinely would like to get 98% or more for the subject, so that I can improve my chances of getting into medical school - my dream is to work for MSF. Anyway, I feel that the resources I currently have are not enough. I have tried to find questions on the sections I do in physics from A-level, but have been unsuccesful so far as I do not know how the A-levels work and which papers will contain what I am looking for. The xtremepapers.com is complicated and difficult for me to understand. The sections I do in Chemistry are:1. Chemical Equilibrium (Le Chateliers laws etc)2. Stoichiometric calculations (%Yield, limiting reagent etc)3. Organic Chemistry4. Rates of Chemical Reactions (Collision theory etc)5. Acids and Bases (Bronsted-Lowry theory, pH calculations etc)6. The fertilizer industry7. RedOx (galvanic and electrolytic cells etc)I attach a few of our recent exam papers so that you may see what type of questions we do. Please assist me in finding questions, papers and resources that will help me. They do not have to be from A-levels, anything that you feel will be of benefit will do.If you feel that the questions in the papers might be of help to you in your studies, please message me and I will give a link that has all my South African resources...Thanks!
