Answer:  Exams will include 40 multiple-choice questions.  Scantron sheets will be provided for students to take the exam.  About half of the questions will come more or less directly from the "sample-questions" below.  The other half will come from lectures and reading, and perhaps two from the internet discussion list for the class. The exams are non-cumulative. Exam 1 is on Chapters 1-5, Exam 2 Chapters 6-10, and Exam 3 Chapters 11-15.

Review questions and past exams are posted at on the home page for the class.

The answers to the review questions will not be posted, except for the "instant-feedback" questions in Excel.  All answers are available from the online lectures and/or the textbook readings. Thus, when you find the answer for posted questions, you will also read material and find answers for other questions likely to be given as well as learn about Environmental Science.
