This class was one of the classes that put my future at risk. If you don't understand a subject I suggest searching for a tutor yourself as when I asked constantly she kept forgetting and never got back to me. This class is basically as self study class in general. She will explain it in a way sometimes, but when she does, it's completely different from the book. When you take exams or tests, there's no point in planning to study your errors as they never get handed back to you (which is close to never). This is not a hate review; This is just my own opinion and point of view of not just mine, but others as well. Before class starts make sure to review all the key points and be prepared for confusion.
