Professor Chi is one of the best professors I've had at UCSB. He genuinely cares about his students so much from what he plays in class to explaining things again. Class was very self-paced and focused on learning. He explains concepts completely, is knowledgeable, and is kind. Take classes with him for sure. Go to lectures, and you will do well.

Dr. Chi is approachable, lenient, and open-minded, with thoroughly explained lectures and generous grading / submission times, none of which included exams. Much of the grade comes from assignments started in section, and while attendance is optional it helps a lot. But some assignments felt superfluous, where even office hours found barely useful.

GOAT. Hands down the best PSTAT professor I've had in UCSB. Knows his materials from top to bottom. Cares about students and very helpful and accessible outside of class and in OH. Because there are no tests, expect some workloads from labs, projects, and Daily Checks. Go to lectures and sections as they help you prepare for all HW. He is very nice

Amazing professor and amazing class. While 126 is usually a theoretical stats class, Chi prioritizes coding applications while going over the theory. His lecture slides are extremely well put together and he elaborates very well. Lecture/section attendance is not mandatory, but assignment answers are often given here so be sure to attend!

Couldn't agree more with the other comments. Peter is a visiting prof, and will likely only be here for the 24-25 academic year. Make sure you take 122 with him if you can! He's incredibly down to earth, caring, hardworking, and helpful in office hours. Don't miss out on this opportunity to meet one of the greats. No tests are a huge plus too!

Peter Chi is a KING. I woke up for his 8AM PSTAT 122 lectures every single day. It is so evident that he pours so much thought and effort into his slides + the overall structure of his class. Everything he goes over in class is meaningful and all ties together. Your time and attention will be respected and worth spending.

He's one of the most caring professors I've ever had. He's super nice to all his students and answers questions in a super digestible way. Attendance isn't mandatory, but it helps so much. You can tell he put a lot of effort into all his notes, class examples, labs, etc. He's an amazing professor that I would take again in a heartbeat. NO TESTS!!!
