Here it is KDC and Rayzo:
Maths - If maths is harder than English for you (like me), I suggest you do a LOT of practice. Revise the Yr 8 curriculum/crucial concepts and also the material for two years ahead! (For this year it was not really required, as it contained Yr 8 content only).
Quantitative Reasoning - This was definitely the hardest for me. Master number sequences and relationships, ratio, proportion and rates, spatial reasoning etc. Know which ones to skip and do not spend long figuring out how to solve a question.
Good luck with your preparation π
Feel free to ask any other doubts if this does not fully answer your questions π
