maybecoooked In terms of the exam, most people aren't used to the time pressure so practicing as many tests as you can is very beneficial. Just revise your year 8-9 science as well, that can prove to be useful. I also watched a bunch of science youtube vids (veritasium, vsauce, numberphile, startalk, amoeba sisters, action lab, kurzgesagt, etc), those videos helped me understand some crucial concepts in science and its use in the real world. Try and get a few writing pieces done for the information and the report sections, I stole some prompts from my friend lol, but you can just use chatgpt. Science reasoning was basically just logical reasoning, the science ICAS tests are really similar so practice a ton of those. And for maths and NR... just grind tests. Lots of people are asking about what types of questions come on the maths sections especially, and I'll just say that it was not anything to stress about. It is about the same difficulty as a practice year 8 Hendersons test, so if you just keep practicing then you'll be good to go.
After you pass the exam, you'll be invited to the interview stage. PLS don't be like me and rush your CV in the last 5 mins!! For the CV, I just put a bunch of sport/academic/community-service/leadership achievements that I had. It can be really helpful to join some clubs and competitions early on, so that you have more to put down in your CV. Personally, I don't think my CV was the best or anything, but what I did do really well on was the one on one interview. My best advice for the interview process is to just show your passion to the interviewer and treat the interviewer as a friend rather than going full on professional. They just want to get to know YOU, so show them who you are.
Yeah, so those are my tips... good luck!
