Would take again

His lectures were very monotonous and hard to follow. However, the homework was easy, and every exam was just questions taken straight from the homework. If you can do the homework and understand it, you will get an A. He really isn't as bad as everyone says.

I took this professor 2 years ago and still get PTSD when I see his name. He talks so quiet and has an accent it is very hard to keep up with what he is saying. If you want to stay sane do not take this professor
