Awful
I recommend that you reconsider taking Sonbuchner's class. He flies through the TLOs, and he makes things more confusing because he never gets them right the first time around. If you have questions he gets frustrated because he is ready to move on. He doesn't make the online quiz, so he says he can't help with it, even though he should know the material. Sonbuchner is also very slow when it comes to giving the grades back, I took my final on 12/16 yet I didn't receive my grade until 12/30.
