I’m sorry but that’s not accurate at all. It means that your test score is at the point where it makes you a competitive applicant, but it in no way ensures admission to any of those schools. Even among 2400 scorers who apply I believe the admit rate is below 15% at HYPS. Regardless of your stats, if you’re aiming for top 20 schools cast a very wide net and consider it a success if you are accepted into even one of them, as there are thousands every year who are academically qualified and competitive but are unable to find an acceptance beyond their safety.
