Quarters is a system of academic time divisions, typically used in higher education, where the academic year is divided into distinct periods or "quarters" instead of traditional semesters or trimesters. Each quarter is usually 10 to 12 weeks long and allows students to focus intensively on a smaller set of courses during that time. The quarters system provides greater flexibility, allowing students to take more courses throughout the year and potentially graduate more quickly. It is commonly used in universities and colleges, especially in countries like the United States, to accommodate various academic and scheduling needs.
