Reviews of professor Lin Si

Emma will test your patience. Make sure to ALWAYS wear your goggles and get with your partner to complete post-lab questions. There are two formal lab reports due with labs. My partner and I were in class no longer than an hour usually.

Look, if you're a brilliant student in chemistry then this would be a breeze for you but if not, then do not expect an A or hardly a B. This course is tough and since it's chemistry, the teachers can't help much, you gotta do everything by yourself. She's a tough grader, there's huge homework and you wouldn't understand much.

very lecture-heavy. a generally difficult class to take but she doesn't make it any more difficult. I would recommend you read or scan through the book to help your understanding. 
occasionally offers extra credit but exams are the only form of grades you receive. 
she offers study guides that are similar to the test. I always appreciated those.

She is very caring. Her exam questions are almost the same as the practice exams. Shes also very great with the lab class.

Although attendance is optional I would suggest attending since she always goes over many examples in class, and she is always happy to answer questions. The tests were very easy, she provides a study guide for all of them, and they are all 20 questions, and multiple choice. She even provides extra credit that you can do if needed.
