Hey guys.
For bio, best thing is to get a very good set of summary notes for yourself from multiple resources (tsfx notes, tutor notes, text book). This set of notes should be king. Use it for solid revision of concepts before the exam.
Next, use both NEAP and A+ (not checkpoints) for SAC revision. If you're SAC is not exam style question based, then really try to get an understanding of scientific method and read deeply into the topic under question. (e.g: for a SAC on thermoregulation, i read really really deeply into various different aspects of thermoregulation, including from unit 1 and 2, and also random books from library). Bio SACs will often go deep into a very specific area of the course in the form of an experiment or prac.
For the exam, do at least 20, if not 30 exams for each unit. Repeat the VCAA exams, until your living and breathing VCAA. It's best to have a very solid understanding of VCAA and its question styles and style of approach to testing youre knowledge. Exams also help with exposure to various situations, and chances are that in the real thing you won't be aplying knowledge to something completely foreign, but something youv'e seen before.
As you do exams, regularly revise notes as well as make a log book of the errors (conceptual errors and careless errors) that you made in your trial exams. Revise the log book regularly as well. In the log book, also include model answers for common question types (transcription, translation, speciation etc.).
Lastly, motivation and mindset are the most important thing before the exam. Keep a cool head, stay positive, and do your best.
Good luck
