Test #1 Study Guide

The basic for­mat of all tests for this course is a two-part test:

Page 1 will be mul­ti­ple choice, and must be completed before going on to page 2. Page 2 contains sev­eral free-response questions. These may be discussion ques­tions or small prob­lems to solve.

This test will be closed-book, closed-note. Calculators are not allowed on the test.

Ques­tions on the test come from mul­ti­ple sources:

  • Digital textbook readings, including all items linked from the digital textbook for the sections covered
  • In-class activities and homework assignments, including specific readings related to those assignments
  • Course library resources

To do well on the exam, it is impor­tant that you:

  • Read each ques­tion carefully.
  • Answer only the ques­tion that is asked; par­tic­u­larly with the sec­ond part, do not spend your time try­ing to do more than the question states.
  • Ask for clar­i­fi­ca­tion on any ques­tion that you don’t understand.
