She can be mean or nice, it depends on how the class is treating her. but is was always there to help me
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.

Seems mean at first but actually very nice, helpful, great prep for PDEs!
