Reviews of professor Chenxi Qiu

Rating: 4.0/5, difficulty: 2.0/5
Though he has a fast accent, he doesn't tend to overcomplicate PDS lecture material. Exams & Pop-Quizzes are open-note. A textbook is used but not required. Do the homework and you'll succeed, as test questions are akin to HW problems. Often ends class a few minutes early & is available for help.

IF you would like or NEED to understand Data Structures, get ready to read. Being from China, Qiu has a thick accent and is very monotone. He is also very redundant in the way he lectures. HOWEVER, if you really need an A, he pretty much hands it to you long as his tests continue to be open notes and you do the his homework.

Professor Qiu is amazing. His class is easy to understand and he is very helpful outside of class, too. He cares about his students and ensures that everyone is able to understand the material. His tests and quizzes are open book too! Would definitely take again!

This class is honestly very confusing. It's easy the first week, and then the difficulty gets really difficult. Professor has a very thick Chinese accent so class can be very hard to follow and properly understand. I pretty much sat through class listening to him but not comprehending anything. Would not recommend.

Helpful outside of class. Exams are open note. Pop quizzes are an easy A if you do the homework.
