After taking two Astronomy classes with Applegate, I strongly suggest this class to anybody wanting to boost up their GPA. There is absolutely no homework, but it is vital that you just SHOW UP to lecture. Applegate writes all the notes you need on the board, so you don't even need to listen to him, just write down what he says and pay attention when you are interested. There is absolutely no homework, don't even bother buying the book. His midterms are literally his problem sets, with one or two added questions. He is a very charming man, and his jokes start to grow on you. TAKE THIS CLASS IF YOU WANT AN EASY A.
