User:Marshallsumter/Radiation astronomy/Courses/Principles/Hourly 3

Principles of radiation astronomy is a course of forty-eight lectures, sixteen mini-lectures for quiz sections, three hourly quizzes that are timed at an hour, a mid-term that covers the first half of the course, and a final which covers everything in the course. This is the third of three hourlies. It covers the third sixteen lectures, the third set of five mini-lectures, problem sets, lessons, and laboratories.

You are free to take this quiz based on these at any time.

To improve your score, read and study the lectures and the rest, the links contained within, listed under See also, External links, and in the template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lectures and resources available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!
