  • The lab was straightforward and interesting. The experiments we did were relevant to what we learned in CHEM 120 and were somewhat interesting. It was fun to work with my partner and have some fun doing the experiments, my TA was nice and the mood of the lab was very relaxed. There were some hiccups when some experiments were a little drawn out and it looked like it would take forever to finish a particular experiment (particularly the titration experiment) and there was quite a bit of time invested writing out a procedure and doing pre-lab quizzes. The course consisted of five labs, each with a pre-lab quiz to be completed 24 hours ahead of the scheduled lab session, writing out the…

  • Pretty basic lab course. Experiments weren’t too rigorous and set up a good foundation for future years. 30% were lab reports, 20% pre-lab quizzes, 10% in-lab performance mark and a 40% exam. Exam wasn’t too bad, just review your lab book thoroughly. Decent course, instructor is very nice.

  • Clearly organized, pre and post lab reports are very time consuming but fairly easy. There are videos for each experiment and the lab book explains the procedure and the theory very clearly. The learn page and overall nature of the experiments were also very organized (unlike BioL 130L). I actually felt like I learned something at the end of this lab regarding both the experiments and perfecting use of equipment. The final was fair and the pre labs/post labs prepared us for it. Sue is very kind and funny, you would be lucky to have her as your instructor.

  • Exceptionally organized course, I appreciate Sue so much for that. Everything you need to know for the lab reports and pre-lab assignments (PLAs) is in the lab manual, on LEARN, or in the experiment videos shared by Sue. You are given one week to complete the PLAs and at the end of the term, you have the opportunity to replace your lowest PLA mark with another assignment. The labs themselves are also quite enjoyable. For the last lab though, be sure to read and understand the post-lab report in advance, as you will be expected to submit it by the end of the class. As for the final exam, it was truly not bad at all. I remember reading older reviews and panicking on the day of my exam, but it…

  • Good luck if you have a bad TA. Can be easy depending on which TA you have but if you get an annoying TA goodluck.

u/Dimtar_: “CHEM 120L is “required to be taken concurrently with, or prior to” CHEM 120. (source) so you can’t take the lab in the summer then the course in the fall, but you can do the other way around”

CHEM 120 - How's the first month like? 1 point, 1 comment

“Considering the MWF schedule, how's the course load for Chem 120 like? Is it similar to grade 12 chem or "harder?" Also, are the tutorials mandatory to be in?”

u/CancriClanLives: “The course load was quite light iirc. Chem 120 was the only course I passed on my first term of year one. It really just expands a little bit upon the grade 12 chemistry curriculum. You should be able to pass it no problem along with Chem 120L.”

u/Master_Inspector3718: “From what I’ve heard course load is pretty light. You have full control over how much you fill up your days with extracurriculars”

u/Master_Inspector3718: “Chem120 runs MWF, if you’re taking chem120L that runs biweekly. Depends how you are with time management, keeping up to date with lessons and structuring your day. I found chem120 a heavier course than the hlth courses”

u/Yash93: “TOK + EE will give you 0.5 PHIL 1XX credit. Chem HL will give you credit for CHEM 120, 120L, 123, 123L (essentially 1st year chem for non-chem majors). BIOL HL I believe will give for BIOL 239. More details here: https://uwaterloo.ca/future-students/admissions/ib-transfer-credit”
