Good professor, entertaining to listen to, is very knowledgeable. Head of department, but down to earth and modest during lectures. You should go to lectures. class isn't too hard.

Smart lady. Can be a little intimidating as she has a little bit of grim look all the time. Don't let that get in the way, she is very friendly once she sees your face a few times and is very helpful. Only problem is she can be difficult to seek for help, so email for aptmt. Class isn't too bad, just do hw and see solutions and you are good to go.
