"Yiang Li was a good TA. He is clearly very knowledgeable on the topic and wants students to succeed. He was consistently available and would answer any question a student had."
"my lab section was with Yiang. He was very helpful throughout the quarter. One aspect that contributed most to my learning was the way he structured the lab; he explained the material clearly and often walked through concepts that the instructor moved through more quickly."
"Yiang was very helpful in providing slides and STATA codes during our weekly lab sessions that really helped in figuring out assignments. He was also great at pointing out what sort of wording was important for responses so that we didn't overly attribute/signify certain results. Huge thanks to Yiang for really putting in the hard work of making this class at least more understandable for the coursework."

"Yiang was an effective TA. He helped to understand STATA and core concepts during the lab sessions in a clear way."
