Assignment 4 Due Date

A keen-eyed student recently pointed out to me that Assignment 4 was posted with an incorrect due. I have corrected the problem, resetting the due date to 11:59 PM on Wednesday, February 25th.

Preparing for the Exam on Friday

I have posted this semester's lecture slides and have re-opened the MasteringAstronomy assignments to help you prepare for Exam 1 on Friday. There will be 50 multiple-choice questions given through MasteringAstronomy. Most of the questions are material that we covered on the slides in class, so be sure to review those. Second, re-read the MasteringAstronomy tutorials and assignments. Finally, rereading the Bad Astronomy chapters will also help you with a few questions.
