Both Marzan and Buccafusco are new so I don't have any info on them.
Rudstein is one of those profs you either love or hate. He's tough. More Socratic than most profs at Kent. Out of my class 90, about 4-5 walked away with an A- or above, and has no problems handing out a D. He will specifically tell you that come finals time.
Very specific about what he wants you to write about on his exams. Hates people writing about unnecessary crap. Loves the MPC (you'll know what I'm talking about after a few weeks of class).
Pretty much it in a nutshell.
