i posted this in our 2018 jm thread, but i thought I'd post it here as well for you guys trying out next year:
I'd just like to say, I think you guys are putting way too much into this. The tests (besides maths) aren't something you can prepare for - there aren't questions like 'how many chromosomes in a human gamete cell' or something. (abt the science reasoning) they're not testing your knowledge, they're testing your ability and potential. so personally my advice would be, brush up on maths, keep up with science in the news and build a good general knowledge and don't waste time learning the year 10 science curriculum (like I did lmao!).
but this is just my opinion - anyone else who took the exam, feel free to comment what you think!
