Reviews of professor Lingfeng Liu

Rating: 5.0/5, difficulty: 4.0/5
15% of grade was homework, 24 points of extra credit was given, and lowest midterm could be dropped. After those grade boosters, the curve was as follows: >91 A+, 91-86 A, 86-81 A-, 81-76 B+, 76-73 B, 73-69.5 B-, 69.5-65 C+, 65-55 C. Exams are very very very difficult though. Overall, if you can stay decently above the average you should get an A

OChem is hard regardless of who you take, but Kitty makes it easier. She gives homework that counts toward your grade which a lot of profs don't do. The exams are very hard but the curve at the end of the year is amazing. Lectures are recorded, but going to lecture and recitation is helpful. She has a lot of TAs that hold office hours to help you

I never met Kitty, but she ran our ochem lab. The course page was always organized, it's clear from her announcements that she cares about her students and wants them to succeed. This course is not easy by any means, but I think I am better for it. Despite number grades, the course is heavily curved so most people do very well. TAKE SARA AS YOUR TA

Kitty's really sweet but her lectures can be a little boring. She spends a lot of time on topics other classes won't even cover. Homework makes up a good part of your grade, but you'll have to do about 40 achieve questions every chapter.  She gives you the option to drop your lowest of 3 exams. 55+ was a C, 87+ was an A. Aidan is a great TA.

Antibiotic Discovery Lab was super fun, and there was a very relaxed atmosphere unlike bio labs. Quizzes are HARD but studying pays off. Lab is fairly disorganized but manageable and I do not regret taking this class. Kitty is lovely, sometimes hard to follow as lecture portions end up being more than 1.5hrs long at times.

Kitty is the best professor for Ochem 1. She truly cares about her students and wants us all to succeed. A lot of practice is given for all units and practice tests are given before exams. The tests are usually harder and she likes to test on exceptions to rules. However, this class is not meant to be easy so be ready to work hard.

Lectures pretty much useless. She rarely draws the mechanisms and just reads slides. She is so kind and approachable.Teaches everything like review. Exams are fair and similar to rec. Gives opportunities for extra credit. She doesn't curve until the very end so you never know where you stand. Homework is nothing like exams, but must do for points

She speeds through lectures without going into enough detail to understand what's happening. When you fall behind she will only talk for 30 seconds about an important topic. Her exams are difficult and don't match the difficulty of the homework or textbook probs. Her rec worksheets are the best thing to prep for her exams. She is very kind tho
