“I would say that more RY are from brisk then all the other yeshivos combined.”
I would say you are 10-20 years too late. Since there are no “tests” to get in, you really don’t know what you will get down the line.
But from the way you speak / write (RY, no less), I’m willing to bet that you’re not the parent of a “great girl with sterling midos”
I think you’re a Brisk grad (or wanna be) and are testing the market conditions.
Best of luck either way.
