    "comment": "He was a little hard to understand and his lectures were taken essentially straight out of the textbook which was frustrating. Sometimes there were typos in his slides which were not always corrected during lecture, so if a student didn't notice the typo, they'd be screwed. However, he genuinely cares about his students, and is very accommodating.",

He is also very caring and considerate to extenuating circumstances that students may experience. I once had a problem with my internet while I was trying to finish an exam. Chen didn't hesitate to work things out. Love this guy!!!!!",
