Reviews of professor Ran Dai

Rating: 2.0/5, difficulty: 4.0/5
You will learn nothing from the lectures. Lecture notes pretty useless too. But she's helpful in office hours. Good luck.

Ran Dai is simply the worst professor I have ever had. Although the class is easy enough due to extra credit opportunities, It is the worst academic experience I have had at OSU by far. Dr. Dai is extremely bad at communicating information to students and you will feel lost during pretty much every lecture.

So the lectures are pointless, she just puts her head down and talk at her iPad. The posted notes are virtually impossible to follow. Be prepared to learn from someone else. Nice person though.
