Taaaa76 I did use checkpoints a few times. They're helpful, but because they're VCAA questions, they might come up again in the practice exams you do. I also used the AtarNotes practice questions and found them really helpful. However, it's not essential.
I can't remember specific answer "formulas" but if you read enough answers, try pinpointing each mark. "Formulas" are good for process questions, such as transcription where you have initiation, elongation and termination (same for translation), and natural selection where you have a selection pressure, selective advantage, and specific phenotypes/genotypes that are favoured (and thus certain traits are passed down, etc.). You could also try creating flow charts for these processes so you can see how you could break down your answers to those longer questions specifically about biological processes.
