Reviews of professor Tommi Koskinen

Rating: 4.0/5, difficulty: 4.0/5
Tommi is a very kind professor who is very passionate about science, but the material is hard and often confusing. He goes very fast during his lectures but thankfully, he uploads his notes online. Daily clicker questions for attendance. Important to do well on homework. Don't have to take the final if you do the term project!

Professor Koskinen is one great professor. I have never been interested in astronomy, but I can promise you that as long as you are actively listening you will do good. This class is definitely not an essay A and there are 3 big quizzes, but if you go to class for the review he adds extra credit! he also offers extra credit on each homework!

It is more work than the other 170s that my friends took but it taught me a lot and was very interesting. I recommend showing up to office hours if you get behind since he and his TAs were helpful.
