Hey everyone, it is really hard to wrap you head around but after reading this whole forum i have figured it out and i hope this helps xx.
In your hsc you have your internal mark: To begin with your internal mark no one cares about, it is your RANK that matters, your rank is calculated against your own schools cohort (just the kids in your school) and how well you do in each exam and then is averaged out. (e.g. you get 75% in your first exam and that ranks you 3rd but then in the next exam you get 60% and everyone below you does better you get dropped to 10th, however this goes up and down based on how well you do compared to everyone else) . this includes all in class exams, hand in's and trials. pretty much in the last 4 terms of school determines your rank. NOW this rank is the KEY to life. once you complete trails (the last chance you have to change your rank) your rank will be fixed in place. For example in legal you rank 10/30 and got a 70%.
It now moves onto the hsc and you smash it! you end up getting a RAW mark of 89% in legal and life is great!
Lets say in the hsc exam your rank stays at 10/30 even though you did better so did everyone else your internal mark with then change to 89%.
Your actual internal mark is NOT used it is your rank that is used. Your rank internally is the grade you will get who ever ranks that in their hsc.
Eg. Your rank internally is 10/30 for legal and in the exam you do shit and become ranked 29/30 your internal mark will still be equivalent to the persons grade that came 10/30 .
THIS is why you have to be competitive in class and as soon as trials are over share EVERYTHING!
and that is your internal mark ^
You also have your external hsc/raw mark: Your raw hsc mark and it is the actual mark you get in the hsc exam, does not change what so ever, what you get is what you get and it is fixed and will not go up of down. this is the RAW exam mark.
Now we add the rank mark. and raw hsc mark , find the average and that is the atar.
Eg.
Your rank 10/30 for legal but come 15/30 in the hsc.
The person who came 10/30 in the exam got a mark of 90%
and your personal rank of 15/30 got 80%
your internal with be changed to 90% and your atar will be an average of the two.
If your coming first in a subject internally then who ever gets ranked the highest grade in the exam will then become your internal exam mark.
if you are ranked low, work hard to move up the ranks before trails end.
