  • Interesting course and straight forward, material is not hard to understand. My prof was Trevor Manning, he is really nice and approachable. There were 2 assignments each worth 25%, super easy to get a 90+ in if you put in the effort. Midterm (15%) and final exam (30%) were hard bc there's so much information and everything is fair game on both tests. Bc of this, I wouldn't say this is a bird course at all, you have to put in the effort if you want a high mark. I did not find it necessary to come to class bc the slide sets are so dense. Class is one 3hr lecture per week, but almost always finished in 2 hrs. Course is overall light workload, but don't underestimate midterm/exam.

  • So much content... midterm and final are hard, but assignments are not difficult to get 100% in if you put the work in. Definitely put your time into the assignments as they are worth the most.

  • It was interesting but very informative, a large amount of information to learn and know for the tests. 3 tests, no exams, non cumulative tests.

  • Definitely challenging, but nowhere near impossible. When I took it, it was 2 assignments, a midterm, and an exam. Assignments took a LONG time, so you should start 2-3 weeks in advance, but they weren't harshly marked. The midterm and exam were straightforward; study for them like you would a bio class.
    Dr. Manning wants his students to do well, so definitely approach him if you have questions.

  • Prof was Trevor Manning and really cared about his students and wanted us to succeed, however the content was challenging, especially the final. 3 hour classes at night were also difficult to stay concentrated in.
