I think his tests were all pretty fair and that the averages should have been much higher. I'm not one of the people that did really well in this class either, I got a B. Maybe the reason the scores were so low was because of the ambiguity of some of the questions? He was not bad at teaching but sometimes it was hard to understand what he was saying because of his accent/fast talk.
Winter 2023 - This class is interesting, to say the least. I personally didn't like the professor that much; his notes were always messy and unclear at times, all homework and exams were pretty hard and the textbook tended to have not many good examples for the types of questions we were given, and he was overall not clear/helpful when directly asked. My TA, Alexander, was outstanding. His discussion sections were great for getting good examples and a general review of what the professor taught poorly. Most people rate this class great due to the pre-applied curve, that is if you get over a 50%, that is passing (C-). Although it is nice, the grading is extremely strict, especially that they will take OFF points if you put wrong work down, so you could technically get negative points (yes you read that right). Midterms are only one hour, and the final was only 2 hours instead of the allotted 3, which made it a time crunch for the amount of questions given. As long as you do well on the homework and aim to get 50% on the exam, you'll be good grade wise, but the class was a pain to get through in the very least. Last thing, the material for the last three weeks of the course is extremely rushed if taken in the Winter quarter due to the holidays, but half of the final was on it. I would recommend taking it Spring as it has the least amount of holidays, so discussions and lectures aren't cut short.
Lectures are horrible. He's extremely talented at putting people to sleep. Lectures follow the textbook pretty closely, but quizzes and tests seem to have next to nothing to do with anything. They cover the topics covered in class, but the questions themselves are often something obscure and never mentioned. By week 5 or so, only half the class show up to lectures. Take at your own risk.
