Mrs. Hartwell is preparing her class to take the Big Test. Knowing they have studied and are well-prepared, she helps the students practice how to sit quietly, fill in the bubbles, and follow the directions.

As her students grow increasingly anxious about the Big Test, Mrs. Hartwell realizes she has to teach the most valuable test-taking skill of all: learning to relax!
