Fall 2018 - The content you learn in this class is very interesting malaria, leishmaniasis, worms etc. However, the content is overshadowed through the dry lectures, tiny details, and little help from outside resources as most of the science learned in this class is very experimental and thus not very extensively studied or made available. Campbell was a very dry lecturer, his portion of the class was very detailed and memorization based so you have to know everything. I would recommend taking this class if you like learning about diseases, the average for the final was a 54% take that as how tedious this class could be. At least the tests weren't cumulative essentially it was 3 midterms, there are better MIMG electives to take in the winter.
I liked her a lot- definitely not absentminded. She doesn't care how much you know about the diseases and the symptoms- she cares more about the science and experimentation that leads to getting the results that exist. You will have to design experiments on her exam and be presented with new data. Make sure you read the articles she assigns ("readings") because there will be a question about it on the exam.
Johnson's lectures are well organized and straight to the point. Her final is really nice, because it isn't straight memorization. I made sure I understood all the main concepts and experiments that she taught, without memorizing every little detail and did really well. Her office hours are also really helpful and she's pretty funny. I'd highly recommend this class. I don't think the curve is that bad. I did exactly average on the midterm and I still ended up with an A in this class.
Fall 2021 - I was scared to take this class with her and Campbell because of the other reviews, and I'm not going to lie, it's a tough class, but it's manageable. Tests involve a lot of memorization (were in-person), so if you're good at that, you'll be fine. Workload is low besides studying. Content can be overwhelming and tedious sometimes but it is actually pretty interesting other times (parasites are cool/freaky!). Both professors are friendly, care about your learning, and are passionate about the material. Dr. Johnson has the better, more clear, lectures. Class is curved so about 25% of students get As and majority get Bs.
It is easy to tell that Dr. Simpson loves what he does. He does, however, seem pretty absent minded and goes off on tangents. He doesn't seem that approachable, but he's a good teacher. Don't get too worried about not understanding a lot of stuff he teaches- he really is only concerned that you know the gritty details on his slides such as diseases, scientists, etc. He won't ask you to design an experiment on an exam- this is what Dr. Johnson does.
