Final was very hard to study for, as you have little to no idea what it will be on. Make sure you have a 100% in the grade book before the final, so don't miss more than 2 quizzes. Overall, pretty chill class until finals week, where you basically have to teach yourself all the material.

Very mediocre guy... not great at explaining concepts and spent a lot of time on topics we were never tested on. Slideshows were mostly textbook screenshots. Class was nice during the quarter (no HW or midterms) which was nice but caused a lot of fear and stress during finals. He seems nice but seems to put MINIMAL effort into the class.

His lecture style is very fast paced and leaves gaps in understanding. While he suggests that there is no need to use the textbook as all information will be covered in class, the only reason I was able to succeed was to teach myself the entire course from the textbook as his slides only contained images with little explanation. He's enthusiastic

There were 6 open-note/internet pop quizzes (only grades 4) for 40% and a final for 60% (allowed one double-sided sheet). His lecture notes were just ok. Be prepared to study and learn on your own time. Biggest issue was the final (needed to know specific details not emphasized in class, while other topics (nucleic acids/lipids/carbs) were ignored)

This class was so hard, I studied every week and still struggled so much with the final. They said the final was easy but the questions were nothing like the practice ones he gave us. Also he literally told us that most of us would fail one question and still put it on the exam?? Take the bio version if you can!

Lecture slides (no recorded vids) are screenshots of textbook and they provide almost no information. Pop quizzes = 4 x 10%, Final exam = 60%. Expect the Final to be much harder than the practice (barely any of them), to which he claims "youll be surprised by how easy the final is". The keys to these practice were also frequently incorrect?!?
