American studying overseas

I am a US citizen studying in Australia and want to go to college in America. I sat my ACT and am happy with my score and won’t be taking it again. I am studying for my final year exams in Australia which decide if I get accepted into university in Australia - different system here and university admission is based purely on these exam results (no GPA, essay etc) . Do you know if colleges take into account an overseas student 's extra workload when looking at their ACT score bearing in mind we are fully focused on our end of year exams and can do little to no prep for the standardized test. Thanks

Lots of students in US high schools have a big work load, too. So no need to make a big deal about it.

I have 2 kids. One kid did zero prep for the SAT, and the other just did 4 free practice tests that he downloaded from the College Board’s website. They both did fine.
