which unis are you planning to apply to? have you applied to any yet [in part or completely]?
my family is pushing me to apply for harvard, yale and princeton. honestly, i'm hoping they won't accept me -- i really want to stay in australia for my undergraduate.
an ATAR of 95 still sounds quite acceptable - the websites i've read up [regarding only the schools above] only show that the majority of accepted students are in the top decile [tenth]. still, they do accept a decent number from the top quartile too.
they would probably regard the SAT and the ATAR on an equal par ... although i guess it does depend on their opinion of our education system!
basically what i've heard is that since they consider so many students of such a high standard, they look for students who are able to bring something unique to the university. i think i read on one of the brochures [princeton?] that they'll look for a very well-rounded person, or a person who is highly talented in a particular area such as academics, or sports, or cultural life.
i hope all goes well for you =)
