For premilinary, remeber the different types of bonding hydrogen bonding, covalent bonding ( when electrons completely their outer shelll, ie. 8 electrons), inter and intra molecular bonding, chemistry of certain atoms, molecular bonding, physical and chemical properities, then open your textbook, study the shit there and suck up to your teachers, that wahy there their to help you.
your will learn all these again in year 12, at some point and make sure you can balance you equations and write them out properly, otherwise how your gona support you answers.
I never lost a single mark, if I do, which I never will... pay attendtion to the question and answer it proplerly, look at the verb, memorize all you chemistry notes by heart, that way you can get full marks easily. Good luck, now
Ask me, if you have a question, don't forget chemistry is easy easy easy as, just learn you notes properly and do ebough examples till you can't sleep, study 10 hours a day like me, become genius with a big brain and solve harder maths questions and learn, how to use you time, aotherwise you fucked.
Go eat healthy, now go to study for 10 hours if you want 99.95,
