Course prerequisites are specific requirements that students must meet before enrolling in a particular course. These can include prior knowledge, skills, or completion of other courses. For example, a mathematics course may require students to have completed algebra before taking calculus. Prerequisites ensure that students have the necessary background to succeed in the course. They help maintain a standard of learning and allow instructors to teach at a level appropriate for all students. Meeting these requirements is essential for a smooth learning experience and better understanding of the course material.
