This class was super fun. I really recommend taking this class with Treu. Sometimes I feel like profs here don't really like having to teach classes. However, Treu was always so enthusiastic about astronomy. You could tell that he was a prof who really liked teaching and working with students. As for the class, the grading scheme was 20% Labs, 20% homework on kudu (the online textbook), 20% for midterm 1, 20% for midterm 2, and 20% for the final. Labs were fairly straightforward. Ask for help from your TA and work with your group mates and you should get close to 100% on the labs. Homework was super easy too. All of the tests were pretty difficult. HOWEVER, the class was curved to compensate for the tricky tests. First of all, the grading scale was generous. 95% is an A+, 90% is an A, 85% is an A- etc. You could also earn up to 5% extra credit by participating on campuswire. Just answer student questions and you'll get the extra credit. Overall, the course was extremely interesting. His slides had a lot of pictures and it was cool to see some of the awesome celestial phenomena. If you have an interest in astronomy, I highly recommend taking this class. Treu was awesome, and it's a fairly easy GE.
