<p>doing well on all these tests will help you get into harvard, but that’s just because harvard more generally values doing really well in stuff–whether amazingly in one or two fields, or to a very high level in several. that seems obvious but a lot of people seem not to get this–what you’re good at doesn’t matter as much as the fact that you’re really good (i know someone here who has the guinness world record for crawling some specified distance in the shortest time, others who excelled in intel/siemens/imo/etc., others who published poetry, others who were scholars of the humanities, others who excelled in music, others who excelled in ballet, some who were exceptional leaders, some with very compelling personal stories, etc.) none of the things OP detailed is “necessary” (except perhaps a high gpa, though neither of the kids coming to harvard from my school next year was valedictorian, both were barely top 10%), because there is no list of boxes harvard checks of in determining who gets admitted.</p>
