I personally thought this instructor was alright. I didn't think the teaching skills weren't too great due to the fact that her lectures were jumpy and all over the place which made it hard to follow. Chm 121 is not that hard of a class if you remember high school chem. Tests were easy-med. She was a very nice lady willing to help find confused.

Her and her lectures are a bit all-over the place. Early in the semester she provides quizzes that you can re-take to prepare you for the exams, but the class got more disorganized towards the end of the semester. MC and the notebook is worth a lot of points and the only other thing you get graded on. She's always available for her office hours.

Joelle is phenomenal teacher, I used to dislike chemistry but Joelle made it easy and fun. The homework load is a lot, but manageable and worth 300 points. Joelle wants you to pass and her exams are almost exactly the same as the problems she goes in lecture. She's also extremely accessible outside of class and ties topics to CHM 1210L well.

Joelle's lectures can sometimes feel confusing and a bit pointless to attend. She uses Mastering Chem for homework and it sometimes can get frustrating because she expects us to learn through mastering chem and does not cover all the topics on the homework. Her study guides are really useful

Joelle is a great chemist. Teacher, not so much. The lectures are messy, and often times have nothing to do with the homework or lab. There is never really an indication of what the things taught in class will be used for in both the homework and lab. If you will take her, be prepared to teach yourself, she barely covers anything on the homework.

Good person with a clear passion for teaching chemistry, just a horrible teacher. Lectures are all over the place and near impossible to follow throughout the lecture. Lectures rarely relate to the homework, which you have to teach yourself. Very particular about formatting on tests, which can be difficult when you had to teach yourself everything.

Opotowsky is really nice and passionate. Her exams were straightforward and she told us exactly what she was looking for. Lectures tend to be a bit messy and all over the place, not in sync with HW, so the HW was a bit difficult to complete sometimes. Make sure to keep up with the homework notebook. Overall, not too bad.

Pros: Not much HW, practice exams are basically the actual exams Cons: Requires students to write their HW in a notebook (it takes ages), will mark off a lot of points for something minuscule on the exams - I say take her if your major is chem-heavy. If not, take an easier professor.

You can tell that she cares for the students but she is very unorganized. It's like she makes things up on the spot (homework,dates for exams) and completely forgets them by the next class period.

She wants you to pass. The homework basically teaches you the material, and she expects you to read the book by yourself. She is a wonderful professor but unorganized. She gives study guides before the exam and the exam is the study guide with new numbers and chemicals so its easy to pass. The notebook is worth a lot and its all mastering chem hw.

Idk how she is for lecture but I had Professor Opotowsky for the CHEM 1210 Lab. I really enjoyed her class and she teaches very clear to the point. There were pop quizzes in the lab but they weren't so hard. Lab reports are graded and she is very helpful if you need to ask for help in the lab. TAKE HER for the lab. Best lab teacher I had so far.

The tests are similar to the study guide. There is a lot of homework and most of it is not taught in class. If you don't follow her methods, you get marked down points. Her grading is not standard so you may lose ten points on a question that someone else loses one on. There was also an added test that was not in the syllabus.
