TLDR: HOW DO I CONVERT MY GRADES TO AN ATAR?

I'm currently a 1st year post secondary student in Canada, but I only have 1 semester's worth of credits. When I asked for info to apply for USyd, I was told that considering this, my high school marks would also be considered. However, since we obviously use a different grading system, I'm having trouble converting my marks to an ATAR. I'm aware that they will do it for me during the actual application process, but I wanted to see for myself to see my chances of getting accepted.

I currently have an offer to another university(but in Canada), and if my ATAR is too low, then it would probably mean that I'm less likely to be accepted to USyd, and that I should just take the offer. Anyways, if anyone has a link to a converter, or knows how to do it, then let me know! And yes, I did try to look this up but I'm fairly confused by this entirely new grading system. Here are the classes and grades for my last year. Also, feel free to share any admission info for USyd (Business)!

Grade/Year 12 Marks:

English: 88

Maths: 85

Health Care: 95
