You'll be getting the low-down on your section's professors from 2L students at the section panels during orientation. I believe it's scheduled for later in the afternoon.
I see by your list that they've shuffled section professors around again. I had Pettit for Contracts and Lawrence for Criminal Law. They're both PHENOMENAL, so congratulations for getting to have them the entire year. You'll be the envy of other sections. You'll see what I mean once the school year starts. Their classes were entertaining, funny, fresh, challenging, and everything you'd want out of law school.
Again, you'll get more details when you start orientation this week. For Barnett, learn to enjoy his favorite topic (himself). Don't know much about Leonard, but my friends who had him last year really liked him a lot. He's one of the younger BU law profs.
