<p>So, can anyone compare these two institutions? Philippine Science High School Main Campus and Illinois Mathematics and Science Academy? The first one, PSHS, is one of the best high schools in the Philippines, whereas IMSA is a very good school, but not really on the top-top in AMERICA. I found many similarities in the two, like how they emphasize math and science, and how they send students to some international contests. Can anyone please search the two if they are not familiar with them and based on their research, can they point out whose better? Admissions to PSHS Main Campus is by having top scores in a national competitive examination while admission in IMSA is by selective enrollment based on student's essay, SAT scores, ECs, and grades. Thank you:) Oh, wait, and both were public residential high schools.</p>
