Physics courses have traditionally used one-chance-only examinations as a probe to tell the professor how much physics each student has learned, with the result that physics examinations have been a common cause of anxiety among undergraduates.

Repeatable equivalent examinations, on the other hand, offer an alternative testing procedure which underscores material not mastered on the first examination and then allows remedial study of this material for the next examination. Furthermore, the thought that it will be possible to have another try at the examination greatly decreases the anxiety associated with examinations. While repeatable examinations are routinely used in Keller-plan courses, this article shows that they can be used in the usual lecture demonstration format as well.
