421 was the only option for the rating, but I took Intro Astrophysics I with Yajie. One of my most chill and lovely physics classes in my life. Absolutely amazing content and explanation. The HW problems can be a bit challenging but go to office hours does help a lot.

yajie is literally amazing--one of the best profs at washu, for sure! the concepts are difficult, but she does a great job simplifying them and makes sure that your grade reflects your hard work. she's super understanding and will not let one bad test define your overall grade! she's very accessible outside of class too

Yajie was a slayful professor. She explained difficult concepts very thoroughly. I learned a lot in this class. Will be taking Physics 422 with her next semester for sure!
