Spring 2021 - Pros: - Very reasonable tests. What appears on his tests is definitely not harder than sample problems in lectures and practice exams (which are straightforward already). - Most of the stuff in his class is really easy if you took AP chem in high school or CHEM 20B before taking this class. - Only one midterm which is worth only 12.5% - Pre labs and post labs are worth a lot of your grade (around 20% and 30% respectively) so as long as you spend enough time on those you will be fine in the class. - Exams aren't open book but you do get to use cheatsheets you created Cons: - He doesn't explain things clearly in his lectures so you have to rely on asking TA's if you have questions - He is unclear abt what he's looking for in your pre and post lab assignments. We were pretty much asking the TA's constantly abt what the prof was looking for in the assignments and sometimes each TA has a different answer. Suggestions: - Do not expect to have a good grade without self-studying. The prof is, again, not a good lecturer. But as long as you understand every concept you will have an A in the class. - Make sure to spend extra time checking your pre and post lab answers they are graded pretty strictly and are worth a lot of your grade. - When the prof says "listen up guys i want you guys to focus" or "this might be on the midterm/final" during a lecture then whatever he says next is HIGHLY likely to be on the upcoming test. - Make sure to do his practice tests because they are extremely similar to what appears on his exams.

I have mixed feelings regarding Professor Walsh. She did go over all the lecture material in class, and she did so efficiently and with enough detail such that it was understandable. Her hand-outs were organized, and she was helpful when you asked her questions. She's really kind of a dork so lecture is a bit dry and she sometimes has students do absurd things (She made one person in our class sit on their butt and fall down the stairs). It kind of felt like a high school class in this respect. She also didn't use the whole time which was somewhat irksome since it was such an effort to wake up and get to this class. But lecture was a worthwhile venture for those who attended. My biggest complaint is with the grading system. It's simply absurd how difficult some TA's are in comparison to others. I ended up with an average of maybe 70% on the labs because my TA would brutally deduct all credit for errors rather than giving any partial credit, which many TA's actually do give. Furthermore, the exam grading key was very specific, I lost 2.5 points out of 48 for not writing "Equivalents of H+" despite the fact that I had the units in all the calculations (and I even cross-cancelled them, I just didn't write it in my final boxed answer). If you want an A in the class you must be very detail oriented and follow directions in the grading rubric PRECISELY, especially if your TA is a strict grader, since it's not curved I was basically screwed. Also they deduct one point for every error with significant figures which is very problematic for people who are not as detail oriented as others. First exam was relatively easy, second exam was much more difficult, but they were doable. The exam seems to have a curve centered around high C, low B, but only because you people really lose tons of points on those small nit-picky things.
