aiming too high? Help!

I live in NY . McGill is more of a safety only because they disregard GPA, and their minimum requirement for an ACT is 28 in arts and sciences… I have 5s in all my APs (so far) and a 34 in the ACT plus v strong recs. I am not sure if they set any store by the essays but it is a fairly strong academic essay (I’m told). Among qualified candidates the accept rate is high (c 40 per cent) . It is a really excellent college, though. It is the case that Canada and UK entrance might suit me better where high marks in exams count and no-one cares about GPA, and being ‘lopsided’ towards humanities is a positive advantage
