Academic concentration refers to a specific field or subject area in which an individual focuses their studies. This could be within a particular major, minor, or specialization at the college level, and typically involves taking several courses related to that discipline. The term can also refer to a group of related subjects, such as history, literature, philosophy, or science, where students take multiple classes in one subject area. In essence, academic concentration is about developing expertise within a specific field through coursework and research.
