Agree with the above.
It varies by college and country, but mostly no, b/c that would be all but impossible to do in a meaningful way, as school systems vary so much across countries. You couldn’t meaningfully compare a US student coming from Oz with one coming from Germany or from Brazil.
Most of the colleges that I know about directly said that (same as in the US), they evaluate in the context of the school (/region/country).
- Ime, applying as a US student overseas does not seem to help in admissions, and HYP will expect that you are a superstar no matter where you are in school (not just GPA).
- Be aware that moving during HS typically dents ECs. It is hard to show leadership when you are arriving at the penultimate year of secondary school. Also, imo colleges are way less impressed that you have handled an international move (or moves, in the case of the Collegekids) than they should be!
That probably all sounds negative- but overall I don’t mean it to! An international move is a great opportunity, and you can have a great, life-changing adventure. But, there may be trade-offs. The biggest one for your family as a whole is possibly losing in-state tuition status for the UCs, b/c US colleges can be so $$$$$. On the other hand, UMelbourne is a great uni, very affordable, only 3 years for most courses, and if you see yourself as an HYP level candidate, probably not a stressful admit. Go to college Down Under & come back to the US for your name-brand grad degree
