  • This is just a bi weekly lab course, with reports due bi weekly. You get to go in the water almost every week to take measurements for the labs and its kind of fun providing its not raining or snowing. Grade consists of 5x15% labs, pre lab quizes worth 2% i think, and an exam worth 15%. You do also get marks for submiting post field work datasheets, i forget how much theyre worth but its not a lot. One of the TA's is really nice with marking and will carry through your mistakes, so if you mess up one question at the beginning, it wont screw you over. The other TA however is ruthless. She will expect you to know the content to her level which i think is extremely unfair, and loves to dock…

  • Randy is the best prof ever! I loved this course it was easy enough to get a high grade if you read the instructions and rubric of assignments (read the rubric on learn before you submit any assignment it really explains what they are looking for in each answer).

  • This course is really cool. Full of tons of really cool concepts and experiences in relation to hydrology. It has similar concepts to 123, and isn’t necessarily too hard if you focus on the key concepts and understand the basics of the course. The tutorials are highly recommended, they were extremely helpful with hints and explanations on the lab assignments. The exam was very fair, and included a small sheet where you could include equations and explanations of concepts, basically if you studied you’d do well. It’s not hard to do well in this course if you at least put in the effort and ask questions.
    The course had bi-weekly field labs, so one week was a lab, and the next was the…

“Is there a rule about how close to the exam a class can give marks back for assignments etc. ?”

u/whodathoe_: “I’m taking EARTH 223 and we just got our lab 4 marks back 2 days ago. Our exam is Wednesday and we still haven’t gotten our lab 5 marks back. All labs are worth 14%. Leaving much room for improvement 👍🏼”
