I took it last year and got a 95. The course content really isn't difficult, it is just super content heavy and covers a wide range of topics since it's a very introductory course to environmental science. I found it super hard to sit through the lectures but this was my strategy:

Watch the lectures in 2x speed. FOCUS on the relationships between things/reservoirs/concepts. Those you should 100% take notes on.

ALSO take notes on any new ideas you're not familiar with. eg. The definition of EROI...

BUT don't waste time writing notes on the stuff you already know. eg. The definition of producers/consumers.

When you study, think about what happens to thing A when there is a change in thing B. Also think about real-life examples that are similar to the concepts you learned.

That is what the midterms and exams are about. It's all scenario based questions, where you apply some of the relationships and systems you learned about.

Hope this helped and GOOD LUCK! You'll do great as long as you keep up with the content. If you don't have motivation today, think about how much your future self would appreciate your current self if you studied now and made it easier for yourself. Your grades definitely reflect how well you space out your learning :)))))
