She's a very nice teacher. She will take her time to help you, but she has high expectations for her students. The tests are very difficult, and you have to give reasoning for all of your answers. Overall she is good, but she grades very tough, and is very thorough in her teaching. She also gives weekly homework assignments.

Her lectures are impossible to follow and she doesnt cover the material necessary to complete homework or tests in class.
