marcel is awesome. okey igbeoli taught half the course and he was a little less fun and a little less clear but still a good prof. hard to compare to marcel.
fun content, but lectures include way more than youll be tested on. tests are very generl, big picture questions. studying requires skills to sort out whats important and what info is extra. pay attention to the MANY practice questions marcel gives in lecture (either verbally or on slides) bcz they are very representative of exam questions. grade was 20% midterm, 40% final, and 40% group project (5% draft, 15% group evaluations, 20% actual product). the project was easy though, i got permission to do it alone and i genuinely think it…Apr 2026 · liked itOn UW FlowRemove this
hands down the best class I took on W26 in my last year !! this class made me like parasites and now self aware when it comes to swimming in lakes/beaches (those parasites will get you omg). breakdown consisted of: group assignment: 25% (draft and final), group evaluation: 15%, midterm: 20%, final: 40%. it is a straightforward class, the midterms are short answer questions so if you answer them properly it is easy to get the mark! I had Dr. Pinheiro since 1st year (biol 110) and he is such a goated prof with Dr. Okey too !! He makes class entertaining and gets you intrigued on each of the parasites he will teach you (we all have toxo atp) group assignments are pretty chill if you've taken…

This is one of the most interesting courses I've taken. The lectures are great. There is one assignment, one midterm and a final. I personally did not like the format of the midterm, as you can write the correct answer, but still score 2/4.

Took this in Winter 2024 with Dr. Pinherio, the marking scheme is 30% final exam, 20% midterm, 4% journal activities, 10% group evaluation, 15% group PSA, 15% group presentation, 3% draft group PSA and 3% draft presentation. The final exam and midterm are completely written short answer with only a handful of questions. You get a lot of different questions to choose from. The midterm and final are straightforward as you are given possible test questions in advance and a cheat sheet. The group project is pretty easy to do well on. You can honestly complete the work yourself. Pretty easy to get a 90+.

This was a really cool and interesting course, I would recommend it. It's Possible to do very well (high 90s) if you study and put in effort. Fully written midterm and final. Two group projects worth 50% of your grade total, but they don't require too much work and you can get 100% on them even with a bad group. Lots of opportunity for class discussion, as Marcel really does try to get you excited and engaged in the content. It's not super easy as there is a lot to know, but the content is interesting, and you get rewarded the more effort you put in.
