schweser 3-day review

anyone have a view on the schweser 3-day review seminars? I’ve been taking a weekly class already so I feel like I know what to focus on. Seems like the 3day review could be useful or end up being a total bust and waste a valuable wknd of studying…probably depends a lot on the instructor. I would go to either NYC or Newark, instructor is Mitch Conover. Is he supposed to be good?
