WILL I STILL GET A GOOD ATAR

[nerdswag]

I am in Year 12 and I exams are in less than 3 months. I am aiming to get an ATAR of at least 80 but I am stressing so bad and I don't think I can get that much. In my SACs I end up doing not so well and I'm afraid it will greatly affect my ATAR. I always stuff up in SACs but I can do VCAA exams with ease (most of the time ). I have been doing A LOT of practice exams since the start of the year. I think I would do better in the exam than I have been doing in SACs. The subjects I do are chemistry, biology, psychology, english and further maths.
These are all my SAC percentages for my subjects so far:
-CHEMISTRY: 55, 50, 50, 70
-BIOLOGY: 64, 57, 50, 80, 50, 63
-PSYCHOLOGY: 60, 88, 54, 86
-FURTHER: 68. 50
-ENGLISH: 50, 60, 50
 
Would I still be able to achieve an ATAR of at least 80 with these marks? How much will my ATAR be pulled down because of this? Please help me guys, I'm really really worried and stressed. Thank you

all about your rank. You could be the highest scoring person in your cohort for those subjects and then blitz the exam - even with 50s-60s on sacs - that will get you a 50 study score.

The ranking system has always ignited fire within me. I know there is hardly any alternatives, but it is especially bitter when it accounts for different abilities. Really doesn't measure work ethic at all.

Also way too complicated, and knowing that anything can happen on a given SAC or Exam day raises multiple conundrums as the nerves increase tenfold when the day remains long and ever so sour.

Furthermore, exams seemingly play a huge trombone whilst the SACs are merely the particles which initiate the atom, that is the exam. I find this stupendously ridiculous, as the exam goes for 2 hours (more or less) and people like me who may have studied heaps can be consumed by the black hole, that is VCAA. I did so much better in the trial exam than the actual VCAA exam last year... Not that I wanted to, but it seems that my run of bad luck continues. So I don't have much confidence in myself at all for a host of reasons.

I am hoping that I am lucky this year, unlike last year which was like living and breathing a comedy.
