Yeshiva gedolah

[1] This contrasts with a Yeshiva Ketana or Mesivta, in which students are typically in the early teens.

There are several differences between yeshiva gedolahs in Israel and the United States, the most obvious one being its name: in the United States, yeshiva gedolahs are referred to as bais medrash, the same name given to Torah study halls.

The day in yeshiva gedolahs (as well as in many mesivtas) is split into three parts, each one known as a seder (plural, sedarim).

This is done both in chavrusa fashion where students pair up to learn, and in a shiur where a rabbi expounds on the Talmud and its commentaries.

[2] The learning at "Night seder", conducted after dinner and continuing into the night, differs between yeshivas, sometimes with the students continuing their studies from first seder and sometimes learning a different gemara than they do the rest of the day.
