Hyperlearning In-Class Casebook
LSAT Diagnostic Exams (6 practice tests)
LSAT Reading Comprehension & Arguments Workbook
LSAT Games & Practice Tests Workbook
These books are good, and they are very helpful. As for the course, I'd say its a waste of time and money (its aimed at getting you in the mid-150s, not 180). $50 or the highest bidder.
