Reviews of professor Lingzi Sang

Rating: 1.0/5, difficulty: 5.0/5
please avoid if possible, tests have no resemblance to provided material, poor lecturer, and I learned the material all from the textbook.

The class is helpful. For her first time teaching, she did a fair job.

Dr. Sang explains concepts clearly. Lectures are enjoyable. Notes are little scattered at the beginning but improves a lot towards the end.

Dr. Sang did a good job of explaining concepts. But sometimes she went through concepts fast so make sure you pay attention. Also, this is when the textbook comes into play. Exams are fair and straightforward as long as you pay attention during her lectures, read the book and ask questions during her office hours. Her lectures go deeper than exams.

I heard Dr. Sang was terrible, but that is not true. She now has her own set of practice questions for each week and uploads them on e-class. Her slides are easy to follow. She spends time doing questions with students. The first midterm was almost identical to the practice problems, so you will be fine if you do them. But you got to put in effort.

Does not seem very knowledgeable about analytical chemistry. Reads off the slide and struggles to explain concepts even during office hours. Was much better in electrochemistry. With this said, exams were on the easier side compared to prior years, and curve was generous (3.3). There seemed to be a disconnect between students and her.

She is a kind person and wonderful instructor. Caring and professional. Lecture notes are organized and very helpful.

The worst prof Ive had in 3 yrs of university. Cannot teach/explain at all! Notes make no sense, gives DIY's that you don't know how to do. Exams too long and not enough time to do it, the questions are unrelated to notes . Exam 2 average was 40%. If it wasnt for CR/NC this term I'd be on probation next year because of her. Avoid like the plague!!

She is my favorite chemistry instructor. Materials are organized and effectively delivered. I appreciate the review session she gave after midterm. Tests are manageable as long as you study the problem sets.

Wallahi she's the worst prof I've ever had in my life. Her exams tested info I'd never even seen before in my life smh. I switched out of Sai Yiu's class into hers and I think it was the biggest L I've ever taken. Her final was the length of a textbook, but I ended up riding the curve to a B-. If you're contemplating taking 102 with her reconsider.
