Newbie I made a comment about chem 3/4 tips on a post on the old forums, I'll copy-paste it here:
*Spam practice exams (especially VCAA), dynamicscience is a good resource
*Practice structural elucidation
*Focus on the explanation questions since they're marked really pedantically like VCE bio
*Be really good with electrolysis and experimental design cuz there is always a massive question on one or both of them on the exam
*Know your organic nomenclature and functional groups
*Understand Le Chat's rule, it's so useful everywhere you go eg determining charge of zwitterion charge when you get to biochem
*Know how to use to electrochemical series
*As an extension to the above, know how to use the data book cuz it's literally Doraemon's pocket
*If you did physics, you can use dimensional analysis (unit cancelling) to check answers and infer formulas that you've forgotten eg if you're asked to find the number of moles of e-s during electrolysis when given the time, current and Faraday's constant without the formula, you would approach it the following way: since current is in A which is in Coulomb per seconds and time is in seconds, multiply these (cancelling the secs) to acquire a quantity in C, which is a unit of charge. Since you're asked for something in mol, and the Faraday's constant is given in C/mol, you divide the charge you've found in your first step by Faraday's constant to cancel out the Cs and move the mol to the numerator side of the fraction, yielding the correct answer.
