It’s not hard. There is no bechina. Your RY gets you in, you call him up and he talks with you for a couple minutes, tells you some details about yeshiva, that’s it, then you show up a day or two before the zman at his house to meet him. Consider carefully whether going there is a good idea for you…
Like someone mentioned above, it’s not hard to get in. But you need to want to be there. It’s boot camp. It’s the navy seals of yeshivos. You’re expected to learn many hours uninterrupted multiple times daily over the few years there. It’s very very intense. There’s lots of pressure. If you can handle that, then go. In public Reb Tzvi is instense and scary. One on one – he is a teddy bear. At the interview he’ll ask why would you want to come, the yeshiva is not for ‘normal ppl’. So you say you want that etc… Reb Tzvi is an awesome person and a huge Baal kishron.
It is intense. The RY is super intense. If you’re not used to the brisker style in shiur and chinuch it will be very, very tough. The guys are mostly, extremely intense. The pressure is and motivation to perform is extreme. You either need to know you can thrive in that environment, or be suuuuuuper chilled, enough that you can be your own person and not get pressured. The hashkafos are intense. It’s important to come with a Rebbi and a clear hashkafa and take what you think is applicable to you from his shmuzin.
