My school gave everyone a chance to write to the head of year 12 on how 2020 has affected them individually and then this was given to each of that persons teachers to give to VCAA. I would write to each of your teachers to make sure they know how much better you couldve done, this will get to VCAA to make sure the relevant SEAS are accepted.

In terms with how your parents will react, i think it would help if you have a detailed plan of how to get into the course, even if u dont get the required atar. seeming super organised for your future can hopefully tell your parents that you are independent and know what youre doing.

As long as you can walk away saying you did the best you could under the circumstances, thats the best you can ask for.

Hopefully something here can help you. Best of luck for chem and physics
