Reviews of professor Rachel O'Brien

Rating: 4.0/5, difficulty: 4.0/5
An hour 20 minute lecture is never fun at 8am, but I did like that she would record the lectures and have short breaks every 20 minutes. Most of the grade does come down to the tests, so study a lot! Also, she posts practice exams and study guides which are pretty helpful! P.S. Check the study guide for extra credit!!

Her class was very hard (maybe it's because of my lack of ability to do chemistry) but I thought her lectures were very helpful. I would often rewatch them to prepare for tests. Her tests are also pretty hard, but if you study hard then you will pass. Definitely a good challenge but she is right for the job and knows her stuff.

Professor O'Brien is one of the best professors I've ever had. IA was definitely the hardest class I've ever taken but O'Brien made it as interesting and doable as possible. The grading was tough and there was a large volume of assignments as well as many hard tests, but I felt like I learned so much in this class. Very accessible outside of class.

Professor O'Brien is one of the BEST professors on campus. She is super sweet, knowledgable and soooo passionate about her teaching. Her lecture is amazing with clear explanations and neat notes. She also weekly collects anonymous questions from students to better prepare for help sessions. IA is a challenging class, but she makes it so enjoyable.

O'Brien is a very nice professor, but IA was one of the hardest classes I've taken. She's teaches an insane amount of material, and only tests you on a tiny fraction of it, but in detail. She is not good at making clear what information is more important than other. However, she is very caring and open to feedback. Just expect a lot of memorization
