Kratzer is a student at Marymount Prep and the captain of their math team. During the competition, he is officially credited as the Marymount Captain.
The team of five students from Marymount Prep went up against the North Shore High School's Mathletes in a math competition. Even though his team answered a few questions correctly, they ultimately lost to the Mathletes in a tie-breaking question when Cady Heron surprisingly gave a correct answer and won the quiz.
