Also interesting, I think is the relationship between a BTL’s success in law school and his ability to learn well, and the type of learning he tends to favor (pilpul, halacha, gemarah, shulchan aruch, ect.).
In my experience, I don’t really see that “good” learners necessarily turn out to be good law students, or vice versa. Though I have found that people who’s learning is heavily focused on halacha and psak seem to do very well in law school.
