Tam Mahu Omer:
I would say he went to a much rougher yeshiva then average, not his specific experience. I could name a yeshiva or two that had similar rules in my day, (like daven in your dorm before walking into BM without a hat on) but most of them are OK (I would think).
frum attorney: When you choose a yeshiva for your child, make sure it fits your hashkafic outlook. You don’t have to send to the best, you have to send to the right one for you and your child.
