She can be mean or nice, it depends on how the class is treating her. but is was always there to help me
She has a really strange style of teaching, but seems to be doing okay...
Ms. Senn is very intimidating if you're not prepared, but she will do her very best to help you... she can be a bit grouchy though. After her class, you WILL know the material quite well.
Teaches a tough course, but is willing to set up help-sessions when you're having difficulties.
Seems mean at first but actually very nice, helpful, great prep for PDEs!
