I second this, need some last minute tips as well!
Hey,
Well, the best way to minimise your mistakes is to take your time first of all to do all the questions and think them through specially with prac. Theory questions, always try to relate it to what principles/qualitative characteristic the questions can relate to. There are many questions that are often asked again and again such as the difference between product and period cost, definition of net realisable value and why it is done (because of conservatism), etc. Revise through unit 4 more than unit 3 as most of the exam will be on unit 4. Read through the chapters and if you have the cambridge vce accounting book, memorize the definitions that are on the side margins of the book. REALLY KNOW YOUR BASICS AS WELL, such as reasons for stock loss/gain, reasons for profit/loss on disposal, definitions of assets, expenses, revenues and liabilities. Also, memorise the format for the reports and ledger accounts (do all of these: stock control, creditors control, debtors control, GST clearing, expenses, revenues) this will help you heaps if there is any budgeting questions because then you know what information to look for rather than hope for the information to stand out to you.
I really hope this helped and tell me if you need any other help
