Reviews of professor Changkun Xie

Rating: 4.0/5, difficulty: 3.0/5
Took him over a summer for Astronomy without a lab portion. Work can be tough if you are not prepared to do a good amount of math. Project over part of the semester is pretty easy if you keep track.

Rating: 4.0/5, difficulty: 3.0/5
Very clear instructions + Grading criteria. As long as you keep up with everything the material is very manageable. A good science class to take if math isn't your strength. only thing is you CANNOT make up any credit for ANY missed deadlines.
