try and know all the standard 2d and 3d shapes (for me that's hard, I'm not good at shapes lol) I know knowing those is like a given but its still good to remember
know these 100% https://www.scribbr.com/statistics/normal-distribution/
I mean same, but if you are looking for ones that are harder I wouldn't do the 2023 one, there was something like 25 people who came first so nesa will be looking to avoid that this year so I can bet it will be a harder exam
