What must students do with grid-it's on the math sections of the psat?

Students must use the grid-ins on the math sections of the PSAT to provide their answers in a specific format. They should fill in the corresponding bubbles for their answers on the answer sheet, ensuring accuracy and clarity. It's important to double-check their work, as incorrect formatting or misaligned bubbles can lead to lost points. Additionally, students should remember that these questions do not provide answer choices, requiring them to solve the problems independently.
