What is the best course for study for navle exam?

VetPrep is a popular study set that is passed from student to student. However, as I was preparing for the NAVLE, I found ZukuReview to work better for me - it's interactive and online as opposed to the hand-held paper flashcards of VetPrep. Either one, or any of the several other review/preparation courses, would be fine - it's mostly about gearing you up and keeping the information you learned over the last four years fresh in your mind.
