A 36 ACT is impressive, but it won’t get you far. I believe Stanford turns down the vast majority of candidates with perfect test scores, and accounting for test variation there is not much if any difference between a 36 and a 35, or a 2400 SAT and a 2350+.
Diversification is also nice, but it doesn’t count for as much as having something that really stands out. All top colleges are dealing with the same problem: 10-20 times more qualified applicants than they can possibly admit, and “bunching” of applicants due to things like test preparation, multiple test taking, superscoring, grade inflation, and other factors.
You have the qualifications to be competitive, but after that it is a crapshoot. There is never any certainty, but the best way to improve your chances beyond those of most qualified applicants is to stand out. This can be done by virtue of excellence in an EC, showing sustained passion, having an interest/skill that sets you apart form the norm, and writing compelling essays.
All top schools want to get to know applicants beyond a list of test scores and achievements. Think about who you are and what makes you different.
