I took Wong for Psych 10 my freshman year and again as a senior for 188B. He gives somewhat challenging exams, given that they're only 30 questions, so you can't miss more than 2 without dropping a letter grade. However, he's quite literally the reason I ended up doing Psych/Cog Sci. He's so engaging, and it's really important to learn about these topics (LGBT+ communities in healthcare, sexual orientation, sex hormones, gender, and sex) if you're pre-med or in general to understand others better. He does talk fast, but if you raise your hand and ask him to slow down or explain something, he will. He's very approachable!

Professor Wong lectures way too fast. He lectures on 2x speed. It was often hard to understand what he was trying to say. He is aware and told many times that his lectures are very unclear but still speeds through lecture slides. Exams were worded weirdly and tested on very small details from the slides. Memorize and learn the slides very well and you will be fine. Don't need the textbook. I depended on the TA for a lot of my understanding of the material.
