I took this class during the summer, so it might be hard to say what he's like during the normal school. I enjoyed Professor Wu's lecture because he focused on the intuition of probability by simplifying concepts down to things like basic dice rolling analogies.

While the proofs might not make sense during the lecture, there were a lot of proofs in the homework, which are explained in the notes he provides. Some homework assignments were challenging, but many of the problems/solutions were also provided in lecture and his online notes.

The final was very straightforward and reflected his course material and homework very well. Many students finished the final within the first thirty minutes of the class.

Professor Wu is an amazing professor. I feel extremely lucky to take his class.

His lectures are usually very engaging, funny and clear. His teaching is relatively slow, but this also gives you sufficient time to digest the material. He emphasizes important concepts over and over throughout the lecture to make sure students understand them, and he never "rush". Attendance makes 5% of your overall grade and participation points are given through pop quiz. Taking notes in class is very important because his homework is largely based on same problems on lecture notes, and his exams are largely based on homework (questions may not be exactly the same, but similar). Therefore If you are able to understand material in the lecture, you will do well on his homework and exams.

Before each exam (one midterm, one final), he gives answer keys to all previous homework assignments. It is critical to review these answer keys and re-study homework problems you missed. Again, his exams are mostly based on his homework problems and questions are straightforward.

I am amazed how much he wants to help students. He stays up really late at night. Even if you send him email at 2AM, he may email you back within five minutes (not always, though). He also answers questions thoroughly during office hours, and he never blame students for asking same questions over and over. More importantly, he gives positive vibes to people. He tries to help students "calm down" by sending positive encouraging messages to students who feel emotional or nervous about exams. He does not release a grading scale, but he gives a generous curve, at least during my quarter.

He does not teach many undergraduate classes very often. However if he ever teaches again in the future, I highly recommend you consider taking him.

Professor Wu is pretty amazing. His lectures are very engaging as he often uses real examples like health related to smoking, gambling, and other interesting examples (I can't remember them off the top of my head...). He is very articulate even though he has a Chinese accent. He makes the material really easy to understand and instills confidence in you that you can actually learn what he is trying to teach!

The great thing about him is that he really cares about his students learning something from his class. He makes the homework a review of the week's lectures. You just need to take good notes to breeze through the homework. This is how homework is supposed to be! Reinforcing the material!

Tests were straightforward. His tests were basically exact problems from the homework and lectures with perhaps one number or an inequality sign changed. If you memorized the homework and lecture notes, you would just need to rewrite it all out to get an A. I forgot some things on both the midterm and final so I didn't do extremely well. Haven't gotten final grades out yet 'cause you know how profs like to do it here....

If he ever teaches again, you MUST take him! Not only will you love statistics afterwards, but it's also an easy class.

Probably one of the nicest professors you will ever experience at UCLA. An amazing teacher!
