Derech Chaim is very focused on learning.
Some of the lower shiurim are on an easier level than you might find at other batei medrashim.
The yeshiva is very serious about the learning on all levels, and talmidim are expected to be full-time learners. College is not allowed.
Several alumni are now rabeim in Derech Chaim and other yeshivos.
The learning and shiurim are all in English.
The bochrim are more Litvish than anything else, but there are a significant number of Chasidim and Sefardim, too.
