I took Astro 3 with Saltzberg, and contrary to what the person below me says, I absolutely loved him. He was passionate, caring, and most importantly, funny.

He genuienly cares about you if he sees you're willing to make an effort to learn the material. He wont give you an A, but if you do what he tells you to do, you're pretty much guaranteed one.

His homework quizzes are a piece of cake as long as you read the book and pay attention in class.

His final was tougher than his midterms, but if you stay on top of the work, you'll not only earn an A, but enjoy the class as well.
