This professor was very nice and very flexible. He was always open to questions and even went the extra mile to remind people to contact him if they needed accommodations. He cared deeply about student understanding and provided very helpful study guides. This class was pretty easy if you put in the effort. Carefully review the study guide and homework questions and you will be just fine. There were homework assignments every week, two midterm exams, and one final exam. Lab was also doable and the TAs were there for help if needed. He also offered 3% extra credit for visiting Griffith Observatory. I recommend this class !

Professor Yu is a nice and engaging professor. He cares deeply about his students, always asks if people have questions. This is a great GE, the professor us very interested in Astronomy. I would be willing to take another course from this professor. Tests aren't too bad as long as you make a quizlet and study it!!

He is super nice, helpful, and a very good professor. He always asks if anyone has questions throughout class. The average for the first midterm was pretty low but it was just because people really didn’t study. If anyone even looked at the study guide they would’ve been fine. Great prof for a GE but go to class and lab.
