semester

A semester is a fixed period within an academic year, typically lasting around 15 to 18 weeks. It's a way schools organize teaching and learning, dividing the year into manageable segments. Most institutions have two main semesters: fall and spring, though some also include a summer session. During each semester, students attend classes, complete coursework, and take exams. This system helps structure the academic calendar, allowing students and faculty to plan their schedules effectively and measure progress over defined intervals.
