Standard doesn't damage your ATAR if you do well in it (points at Drifting's ATAR & results & whatnot)! It will not benefit you as much if you did mediocre in it, IMO (compared to doing mediocre in Advanced) etc.
ANYHOO, to the OP, I recommend this for each subject
ENGLISH STANDARD: picking up a good tutor for English to assist you with preparing you for HSC English (a lot of people don't agree with having English tutors who help you in assisting you in writing your essays but I recommend it if you really want to improve your marks in the short term).
IPT: great work in IPT! Keep it up
SDD: great work in SDD as well
I recommend pushing yourself a little more to hit the consistent 90s and maybe even 95%!
Physics: THIS, I can help with you because I am the worst Physics student I know - I absolutely can not Physics and what helped me the most was reaching out to Physics students and teachers and actively looking for help and learning with them, learning examination techniques and (if you can) picking the most suitable option for you (at my school, they offered Q2Q for my class and there was another class doing Medical - now I knew I had an interest in Medical and I knew it suited my style of exam taking better because it was revolved around just knowing the knowledge and being able to reproduce it all in the exam
despite being looked down on by my class...)
MATHEMATICS ADVANCED: For me, I don't have really extensive advice but do a lot of practise questions, complete all homework (and actively mark it and ask your teacher questions, sacrifice your free time to go to your teacher as well!) and do plenty of past papers a week before each assessment?
MATHEMATICS EXTENSION I: Same goes with Mathematics Extension I, I don't really have a detailed piece of advice, I just remembered that I was determined to not get a report saying 30/50 (60%) and worked my ass off with lots of practice (I practised more MXI over Mathematics at times which drastically improved my MXI mark and tarnished 2U a little, but that was okay for me)
SOR I: Good work in SOR I
Keep up the work with the 85% and 100%
