Dreaded Prof I've seen before

I'm taking a gen chem class this quarter with a teacher I am not a fan of. I had this professor for o-chem, and while I wouldn't say she was the worst teacher I've ever had, I will say every single other teacher I've had was better than her. Every. single. one. I've only written one negative review for those in-class evaluations and it was bestowed upon this teacher, Professor Lazy.

Our homework is online and the exams are written by the interwebz. No office hours, no emails answered, and she's never available before or after class. Lab times are a joke, because she reads the lab to us (are we in kindergarten?) and then leaves. To make it worse, her teaching style is non-existent- she "teaches" by asking questions. How is that helpful?

Prof Lazy: This here is a double bond. Do you think it is stronger or weaker than single bonds?
*crickets*
Prof Lazy: What do you think?
*low murmuring of indecipherable words*
Prof Lazy: Hmm?
Class: mumbling of both yes and no
Prof Lazy: Yes, that's right. Now this here is a triple bond- is it stronger...

What? What's right? No one said anything! They just mumbled "yes" and "no"! Which is the right answer? And why is it stronger? The bloody hell!

If anyone else was teaching this class, I would have taken it with them, even if their degree was in Speech Communications. But no, I'm limited to Prof Lazy and her insane exams. You see, the hazard with not writing your own tests is that the exam you find on the internet may or may not include material you have actually "lectured" on. Thankfully this isn't a problem for Prof Lazy, for she just figures we should know that information empirically. At least the test is open book and notes. Thank God for small favors.
