If you applied to a bunch of top schools, you will probably get into at least 1. But only when you can learn how to spell “universities” correctly first.

It is not a lucky draw that applying to a bunch of reach schools may give you a better chance. Your GPA is good but they would also look at your course rigor. ACT 33 is probably around the average score of students applying to these schools. So your chance would be around their admission rates.
