Coursework is work performed by students or trainees for the purpose of learning. Coursework may be specified and assigned by teachers, or by learning guides in self-taught courses. Coursework can encompass a wide range of activities, including practice, experimentation, research, and writing (e.g., dissertations, book reports, and essays). In the case of students at universities, high schools and middle schools, coursework is often graded and the scores are combined with those of separately assessed exams to determine overall course scores. In contrast to exams, students may be allotted several days or weeks to complete coursework, and are often allowed to use text books, notes, and the Internet for research.
