All the different yeshivos have categories that they fall into. Bais is mostly out of towners. They usually come straight of high school and some of them do really well there if they stay the course. Tj is usually kids with a history or they’re on the way down and if u stay the course after 3 years ull “flip out” and go to the mir. Ohr sameach has a program for everyone although it’s a kiruv program. Keren biyavne is prob one of the top non chareidi yeshivos and they will try to get u yo make aliya. The mir as stated above has a shiur for almost anyone (although the youngest guys there r 20 and most guys 1st get to there at 21) and you also need to be sort of self motivated.
