I am a year 11 student with ADHD, Autism and I have a lot of anxiety about basically everything. Especially exams.
I believe I am quite an intelligent person and I get quite good marks, however, illness and anxiety can drag me down a lot to an extent.
I average around about 87% for general math, 85% for English and Business management, 78% for Systems, 60% for both Physics and chemistry. I am subbing out chemistry for computing, which will be my best subject (Couldn’t do it first semester due to a teacher on long service leave) where I averaged around 98% last year.
I am wanting to get an early entry offer for RMIT for a professional Cyber security course which requires an 83 ATAR, which I think I can easily achieve with effort. The problem for me is that ADHD and Autism play a massive part in exams, where I get nervous for no apparent reason even if I know everything, and ADHD makes sure that I cannot really focus at home as I cannot access meds at night.
My main question is… should I bank on an early offer to help reduce my anxiety? Also, if someone has gone through the same thing as me, what marks did you get? I have not been able to get a lot of help from people around me as they don’t know to much about the system.
Thank you very much for reading so much waffle and have a lovely day or evening.

(Please I need some advice) Worried about Y11 marks for early entry and what I need to achieve to be looked at.

I am a bit worried about y11 marks. I am attempting to go to RMIT for a Cyber Security (Professional) course that requires a 83 ATAR. I average around 90% for general math, 80% for English and Business Management, 75% for system engineering, 60% for Physics and 55% for Chemistry. I have been sick during all of my science SACs which has heavily affected marks. I could not do computing unit 1 due to the teacher being on long service leave, but I am changing chemistry for it. I averaged a 98% last year.
What sorts of marks would help me get an early offer and how much do I need to improve?
I also have extracurricular activities and experience to back me up.
Any advice for me?

(Please give me some pointers I am very anxious)
