If you just need to work on distinctions, I would suggest a private tutor. They can help you create a study schedule, as well as personally go over substantive materials. Also, practicing the MPT and getting a good score there can help you quite a bit.
LawTutors has a New York based office, in the city, and also offers distance tutoring. We also have New York tutors in the Boston area.
