Spring 2025 - Avoid taking this class with her. The lectures were very fast paced, which is somewhat understandable since the class only meets once a week. She dedicates around 30 minutes to work on a problem set worksheet during lecture, but it is difficult to keep up since the lectures are so dense. The lab portion was manageable. However, the exams were unnecessarily complicated and did not reflect the material covered in class. While she provided problem sets and supplemental worksheets, which were already quite challenging, the exams were significantly harder. The midterm average was a D. The final exam was so complex that the entire class was confused, and she had to give a last-minute mini lecture that only made things more unclear. Most students spent the full three hours struggling through the final. Ultimately, take this class with extreme caution. I would not recommend taking her class.

Spring 2022 - I had a very positive experience taking Pang for 14CL, especially after hearing horror stories about Henary. The three hour labs 2 times a week honestly sounded overwhelming, however, its not as bad as some weeks it's just one lab that requires possible 4 hours total. Other weeks we didn't even have to meet for the other section or it would only last 1 hour if you were efficient. The pre and post lab reports were a decent amount of work but the midterm and final were very reasonable if you studied all the content. Additionally if you have a good lab TA like I did (king Brandon Jolly), then you should have close to 100% in you lab category. I ended up only needing to get around a 66% on my final to get an A because the requirement for an A is 90%. Professor Pang teaches very clearly, and is one of the last few good chem professors left as the UCLA chem department falls to shambles.
