Of course a list of Class A vs. Class B yeshivos is not soemthing I’m going to post here, but there are PLENTY of yeshivos today for these boys. As someone posted above, don’t apply to riverdale or philly. As a rule, the older established yeshivos are the ones pursuing the better boys. MOST of the yeshivos opened in the last 10 years are not that type – and there are many.
I was associated with a yeshiva in E.Y. that catered to such boys, and i can think of 5-6 yeshivos that sent there off the top of my head.
