how did you end up starting your revision? i know this is from a while ago and there's only a few days until the exam but personally i find it helpful to:
- go through the syllabus dot point by dot point and see what your strongest and weakest points are so you can work on them (and then do some related practice questions) (even brushing up on dot points you know nothing about for a few minutes can help hugely in the exam: anything is better than nothing
- go through a past/practice paper (untimed/open book so it's less intimidating) and look at the answers to make sure you know how to answer each type of question they throw at
- memorise key terminology from each module
- look at the hsc formula sheet, and ensure you know what each formula means, how to apply it to questions, how to rearrange equations, as well as what formulae AREN'T in the formula sheet (e.g. escape velocity)
- brush up on SI units and conversions!

https://www.bobemeryphysics.com/year-12-physics <- this guy also has some really good worksheets/practice questions for each module with very clear explanations
hopefully that helps somewhat, good luck!!! hope you're not feeling too stressed, we've got this : )
