I just heard from a reliable source that a bachur with a BTL from Darchei Torah in Far Rockaway scored high on his LSATs and just got accepted to Harvard.
(I do not recommend this approach for all.)
ROB, I believe a BTL is a degree that Yeshivos offer which is non-accredited by any recognized national or regional entity, which is supposed to mean the person took enough credits of whatever the Yeshiva offered to satisfy their requirement for something equivalent to a Bachelors degree from a university.
I do not know if these are all learning credits, or some history and philosophy or maybe even some secular courses are required by the Yeshiva. I think it probably depends on the Yeshiva.
