For maths just make sure to know all of year8, year9 and advanced year9 topics, and maybe a bit of year10 too. For vr, there is not much to do just keep doing practice tests and exams, whatever u find online if u don’t have any resources. You can try and find something in the local lobrary if u want but much better would be to buy some practice tests or questions if u can.
