  • The whole course pretty much involved just filling in answers in a lab manual, with one "Water Sampling" group project, which was quite fun. The final was online and was not too difficult. Very easy to do well in this course but it's just boring.

  • Overall an interesting course. It consisted of weekly labs, a final group report and an online exam. The weekly labs were quite easy, a lab manual purchase is available and generally required. Some of the questions can be tricky but Keith or the TA’s have no issue helping out with those questions, and often they’ll omit entire questions if they’re worded funny.
    You can easily work ahead in this course, I managed to dedicate one night and got over half of the labs done and was able to just go to the class and drop it off or ask questions about the ones I was stuck on.

  • Meh. that's how I feel about this course. It is not a typical "Lab" course, you just answer questions every week. The labs were just kinda annoying and some of the questions were just stupid. With that being said, most of the questions weren't difficult to answer, you just need to sit down and do it, then take your questions to the TA on your lab day and go home after 20 minutes. exam was difficult to study for and difficult to write.

  • Boring and pointless. Uses an american book so lots of non-metric calculation and questions regarding TERRORISM.

  • Fake course. The highlight of the course is a water sampling lab where you go to different buildings and outdoor water sources and write a report. I suppose it's significantly better than taking a chem lab.
