A major is a specific area of study that a student focuses on during their college or university education. It typically requires a set number of courses in that subject, allowing students to gain in-depth knowledge and skills. Common majors include Biology, Psychology, and Business Administration. Choosing a major can influence a student's career path and job opportunities after graduation. Some majors are more specialized, while others provide a broad foundation applicable to various fields. Students often declare their major by the end of their second year, although some may change their major as their interests evolve.
