  Designing a one-hour unit test for an introductory physics class can be quite
challenging. We present an efficient format of a one-hour unit test that
utilizes question groups for quantitative free-response problems and a binary
system (True or False) for conceptual questions. This format promotes coherence
and allows the instructor to test a wide variety of topics in a one-hour exam.
For the 4 semesters in which the design has been implemented, average unit test
scores have increased from 76% using traditional test format, to 79% using the
efficient design.
