Overall, an amazing course. I loved every part of it except for ecology, just because of personal preference. The contents are all interesting and explored quite deeply. Boris tends to give you an assignment on a topic that will be covered on the test right before said test. This is useful, it will help you review if you payed attention to the material. Don't underestimate the difficulty and depth that the exam goes into. Use Khan Academy, ChatGPT (to explain concepts) and course note packets/powerpoints to study, I guarantee you'll do great.
