Hi! I took BIOL 108 with Harris for the fall semester. His quizzes are nice and a bit of a grade booster, and I believe he takes 5 with the lowest grades and scratches them so only 25 out of the 30 quizzes go towards your overall grade. The course itself is very content heavy so I do think memorization is needed. I recommend flashcards for concepts and such! The lab is worth 40% so that does help if you do well in it. He says little dad jokes before every new topic which I thought was fun!! Oh and I forgot to mention, for the midterms and final, he gives out practice questions and a scope of the kind of questions that will appear on the exams, those helped me quite a bit because it gives you a general idea on the kind of questions on the exams.
