The exams will probably be a combination of multiple choice, short answer, short essay, and maybe something I haven't thought of yet. Please turn off all cell phones at the start of class. You are busy. Let your friends and family know. Keep up with the reading and assignments.
Astronomy is too difficult of a subject to study all at once just prior to an exam.
Science can be a very hard subject for some people, and they need complete concentration to learn the material. There will be plenty of opportunity for discussion and interaction during the 140 minutes we are together each class. If you feel you are falling asleep in class, be prepared to be singled out by me. Alternatively, you should feel free to step out into the hall and get a breath of air and a drink of water at any time. You are welcome to help each other find answers and discuss approaches to answers.
