Dr. Haynes' class was relatively easy. Providing you pay attention and take notes study you can get a A or B without trying too hard. Lab is extremely easy, but make sure to study like hell for the lab practicles (luckily theres only two). Besides that she's very interesting and smart. As long as you attend classes and keep up with the powerpoint, you're fine. She never made us read the textbook, and everything that was on the exams was covered in her powerpoints.
