Astronomy college course/Lunar Phases/Obsolete quizzes
These quizzes are obsolete because they are incompatible with the software currently used to generate exams. This software requires quizzes without letters (a-e), and also quizzes with the image situated inside the question. These quizzes have the image outside the question. They are good informal exercises for student practice, but cannot easily be made into tests. Except for that, there is nothing wrong with them.
