A "major" is a specific area of study that a college or university student chooses to focus on during their education. It typically involves a set of required courses and electives that provide in-depth knowledge and skills in that subject. Common majors include Biology, Psychology, and Business Administration. Choosing a major is an important decision for students, as it can influence their career paths and job opportunities after graduation. Many institutions offer resources, such as academic advisors, to help students select a major that aligns with their interests and career goals.
