EXAM 1 REVIEW QUESTIONS
Exam 1 will cover Chapters 22 through 26.3 in the Pasachoff text and the
corresponding Online Journey Through Astronomy material as shown in the
course syllabus. The online text includes self
quizzes which are excellent for review. Some more questions similar to the
ones you can expect on the exam can be found here, for each chapter.
The exam will contain only multiple choice or matching questions, but a
variety of question types are included here.
