ummmmm two words "Past papers" Repeatedly do them in you spare time and attempt to understand the concepts without looking at the worked solutions and you'll be set for a band 6 regarded you know your concepts.
well i can tell you that school rank does not matter at all because a fellow student at my school which is ranked 500+ received and atar of 97.8 regardless of the schools rank. My advice is to perform your best and not allow the talk about scaling affect your performance.
the top of the equation is e^3x-4
To find the bottom of the equation all you need to do is differentiate the power of e.
therefore DY/DX of 3x-4=3
And to solve for this problem all you need to do is [e^3x-4/3] with the 2 and 0.
I'd draw pictures:) since there really isn't any point in studying for a subject you know your dropping. Just walk into the exam chill for a bit and walk out or have a nice good sleep if its early.
LOL 70% raw for bio scales to 86% aligned and and if your raw for bio was 85% then you would be looking at around 93-94 . Whilst for business im pretty sure 85% raw is getting you to around 93-94 also so in term of which subject is better, they are both equal but in biology there is more room...
yes they will. They were provided by the 2012 paper and here! http://news.boardofstudies.nsw.edu.au/index.cfm/2013/6/21/Official-Notice-Ratios-in-the-Business-Studies-HSC-examination
90? lol id be surprised if he gets lower than 96.5 honestly that's for sure considering the rank of the school with your ranks, sure some subjects arent the greatest but that english will definately get you around 96.5 or even higher imo:)
