It's the last week of school, and Mrs. Hartwell's class is excited to leave for summer vacation. The only problem is that the kids don't want their teacher to miss them while they're gone. Once again Julie Danneberg and Judy Love bring to life the crazy antics of Mrs. Hartwell and her class and show that teachers and students are more alike than different.

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. She even instructs them on proper morning-of-the-test nutrition. 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!
