I know a bit about Beis.
It is a 4 year program. Many start from the first year, but some do transfer in after 2nd year at other place. Learning is good. There is a heavy midwest presence including boys and rabbis. The people I know that went/ are going there love the place. The guys have a lot of fun but they also learn. Its in Jerusalem but a little far from the Kotel.
If you have any specific questions I’ll try to answer them for you. I personally did not go to Beis, but I considered it and some of my friends went there.
