This rating is not for Bill Wischusen, but for my lab TA, Maria Gavilanez. She was very thorough and went above and beyond for us. The course, however, was a ton of work. We had lab reports due every week (which were graded harshly) along with weekly quizzes from the notes. The quizzes were 10 questions, all fill-in-the-blank and True/False, they were easy if you read the notes before class. Along with these grades, we had 2 oral reports (which were easy As) two exams (fill-in-the-blank and multiple choice, easy only if you study well in advance) and both class and lab participation points. Also, there was a big Independent Project you have to design and complete with your lab group. My TA was lenient with the grading, and very helpful, but it was a very time consuming project. The lecture part of the course was cancelled about half way through the semester and we ended up doing everything in lab, which was nice. If you only need a lab to meet your science requirements, I would advise you go elsewhere. Either that, or make sure you have ample time to dedicate to this course and good group members.
