An Introduction to the Self-Review Library
This archive contains 26 lecture modules, each covering basic topics in introductory astronomy. Our program is geared toward college students, non-science majors taking general education courses in astronomy, but anyone is welcome to use our resources to learn.
If this is your first time working with the self-review library, we recommend reading through several of the first lectures. You might also want to take a quick look through our FAQ. Then log in on the request page, and select a lecture or a series of lectures, and see how much you have learned. There are more than 12,000 astronomy questions available to you, so you can spend as much time as you wish on any topic and always see new questions.
You will be presented with a set of five questions covering material from your selected lecture topics. For each question, you'll have access to a link taking you back to a relevant lecture slide, to review the context of this topic. You'll also have a friendly hint button, to get you started if you are unsure how to approach the problem. Once you answer each question and submit your work, you'll receive feedback on every problem and complete solutions, so that you can check your work.
Try to work in a quiet environment, with no noisy people, television, radio, or social media to distract you. You should keep a calculator handy, in case you want to use one for some of your calculations.
If you are using this self-review library as part of a formal course, you may be taking weekly quizzes as well as reviewing material. Weekly quiz questions are drawn from the same archive as the review materials, so the more you prepare, the more familiar you will be with the material you are asked about on your weekly quizzes. We recommend taking at least 20 review quizzes per week, in preparation for the weekly quizzes.
