Can I get a 40+?? :3

[shinymeowstic]

Hey all!
I've been ranking 1st or 2nd in pretty much all of my sacs, and I have been getting 90+% across the board. I got 90+ in the Core, Matrices, Networks and Business Maths.
I was wondering what I'd need to do to get a 40+? My only concern is my co-hort - I go to Colac Secondary College, and most of my classmates don't do as well as me - will that affect my chances of getting a 40+ ?
What will I need on the exam to get that 40+ I want?
And for studying for the exam - I got a checkpoints book from 2012 and I'll be working on past exams, is there any other advice anyone has for the exam? I'm mainly going to work on my weak points to get them a lot better!

if you rank 1st cohort does not matter. period.

if you are ranked 2nd or lower than yes cohortmight effect you, unless they are likely to outperform you on the exam which means it doesnt matter
