Environmental Science 1B03 You will talk about ecology (very easy to learn), soil and water components (more like geology which I find somewhat interesting and boring at the same time) because there are some parts that discuss some issues in pollution, environmental degradation, and some management (what can you do type of thing). Also last parts of the material is interesting and captive because it covers human population growth, global warming, waste management, etc. Labs are somewhat annoying but is quickly to do because most labs are finished at lab time. There are 1 soil lab and couple of other dry labs (its dry but easy mark you most people in the course got atleast 70%), Easy online quizzes best 1 out of 3 attempts, you can just googled it lol and got atleast 80%!
Essay where you will choose a topic from the list of articles given by the professor/ta, not hectic to do as long as you do it early. It was easily mark by ta even though some people just have worst essay lmao but it was fair because many bonus marks are given. Overall, there is moderate amount of work but is not heavy as other science courses. Environmental Science 1B03 is a mark booster, somewhat interesting, don't buy the textbook, go to class take notes because Bernier final exam is straightforward to the lecture notes.
As for the KIN 1Y03, very interesting but memorization is so heavy and I'm sure that next year it will not be open to other non-science students. Hope this helps
