Parr is a young, new teacher. She mostly recites information from the textbook. She has a fairly positive attitude, but I recommend taking general chemistry from a more experienced instructor. Also, lab and lecture usually don't match-up in meaningful ways.

Most helpful professor! she will sit down with you and explain concepts until you understand them and never make you feel dumb or unworthy of her time. tests cover the same concepts in class just applied to more intricate questions, much like the HW. Not the easiest professor but you truly learn from her, which helps a lot for later sciences

lab and lecture never match up, it doesn't matter which professor you have. she provides lots of examples in class and extra practice problems that all really help. test average used to be significantly lower than Bau's, but it all evens out in the end. it got closer 2nd semester so maybe things have changed by now. curve works out fairly though

If you have no prior knowledge of chemistry, this class will be extremely difficult. She is helpful when it comes to fixing your grade, but when I asked her for help with a concept, she referred me to my book. ALEKS takes up a TON of your time. Her tests were sometimes very similar to her practice tests; at other times, they were wildly different.

She seems nice but her class is terrible. What she talks about in lecture has nothing to do with the exams. She only presents easy stuff in lecture while the exams are ridiculously tricky and there's never enough time to finish. Taking this class discouraged me from further taking chemistry classes. The exams are just really unfair.

I had her for 105a and 105b. She reads pre-made slides from the book for lecture, is quick to rush out of office hours, and makes mistakes on nearly every practice exam. Also, the real exams do not accurately reflect what she attempts to teach, largely due to her being a researcher, and not a teacher. Careful reading other reviews on here, they seem pretty fake.

Dr. Parr is a very clear lecturer. She reads off slides, but goes through problems and is very good at explaining the material. However, she goes through easier examples. The exams are very tricky. If you read the textbook along with class and DO ALL THE PROBLEMS IN THE BOOK (this is very important--you will do well on exams if u do), it's not bad

Be aware that the Chem dept has a limit on the % of A's and B's so, despite any effort you or Dr. Parr makes, there's still going to be a "downward" curve.

Dr. Parr was clear and considerably lenient in her grading. You could drop your lowest score in most assignment categories. Go to the supplemental instruction. Because it's a large class, Dr. Parr can't go through every problem in detail, so that's where the SI fills in. Group labs are the hardest, but most of them are typed and there's no prelab.

Dr. Parr was an amazing chemistry professor. She moves slowly and patiently through the material, so as long as you listen well during lectures, you have to do very little studying outside of class to do well.

Dr. Parr is a great lecturer and makes complex topics clear. We walk through practice problems every session so lectures are engaging and helpful, and they set us up for the test. Ample practice opportunities and no trick questions. Went to her office hrs once and she was nice. Would recommend SI as well just to solidify concepts

CHEM 108 is the chemistry sequence for chemistry & biochemistry majors. The class was not very difficult (other than the beginning part involving MOs), and the exams were fair. However, the final was very dense and hard, so try to do very well before the final. Dr. Parr was our lab instructor, and she was very hands-off. The TAs did the work.

Lectures were concise and to the point. Did not have demonstrations like Dr. Krylov and Dr. Reisler, but was still an engaging lecturer. Her test questions were very fair and covered basically what she covered in lecture. Was responsible for the lab portion of our class for first semester and most of the second semester. Very fair lab grading.

She's great content is based off the lectures. Textbook is needed but she does guided readings for a completion grade. There are so many points that are just given to you by doing the work. The content in my opinion was also super easy so if you do the reading you can probably get away with missing the lecture. Lectures are extremely clear.

Parr's lectures are decent, but she is very helpful when asking specific questions and answering emails.
