School sessions are periods of time during the school year when students attend classes. They usually consist of two semesters, with each semester lasting around 18 weeks. During these sessions, students take classes in various subjects such as math, science, and language arts. Additionally, they may participate in extracurricular activities, such as sports or clubs. The TERMS used to refer to these sessions vary from school to school, but they are commonly referred to as TERMS and classes.
