Reviews of professor Peng Li

Rating: 3.0/5, difficulty: 2.0/5
If you did well in CHEM 116, you'll do well here. An 80% is an A so you don't need to stress too much. Honestly, the only thing Dr. Li is good for is getting the solutions to in-class problems. You can probably teach yourself everything with the notes he provides. Also, the lab is not as bad as everyone says.

CHEM 215 is basically the exact same things as 115/116 except a little more in depth. All of his quizzes and test are very fair and a lot like the practice exams and quizzes. He gives lecture note prior to class which are word for word what he says, but he gives extra examples, not in the notes and they are more in depth and on the exams.

ONLINE CLASS REVIEW: This class was hard. My issue was that all of the math was typed out on slides rather than actually carried out for students to follow the process. The take home assignments are a BIG help, so don't take it for granted. He does send out the zooms videos so you can go back and watch them. He uses lockdown browser. Hit or miss.

Only three quizzes and exams but the class is curved. The material is basically a rehash of gen chem and if you just sit and work at it its not too bad. He provides a pdf of all his lecture notes so you don't have to scramble to write everything down as he lectures, just the example problems. Very friendly and gives plenty of practice problems.

Dr. Li is an alright professor. He is hard to pay attention to (very dull) and lecture attendance truly was not necessary. He posts all the lecture slides which you can read after class. Lab was much more enjoyable and I felt like I actually learned things there as opposed to the lecture hall.

Attendance isn't mandatory in any fashion besides with exams/quizzes. Material is easy to teach yourself with the lecture slides if you miss. Basically more in depth gen chem, material wasn't hard at all. HUGE on significant digits which was so annyoing. 80% was an A so you really don't have to take it that seriously. No suprises on tests.

Pretty avg professor with avg lecture. Wish he can do calculation problems on blackboard instead of showing us ppt slides. You basically learn CHEM 115/116 again in this class. 80% is A in this class. His practice exams are very useful. And lecture exams/quiz are very fair. Study old exams if you can! However the lab sucks. Again the lab sucks!
