Final answer:
Prerequisites are courses or requirements that must be completed before taking a particular course. Corequisites are courses that must be taken at the same time as another course. Advisories are recommendations or suggestions for students before taking a course.
Step-by-step explanation:
Prerequisites are courses or requirements that must be completed before taking a particular course. They are necessary to ensure that students have the foundational knowledge or skills needed to succeed in the higher-level course. For example, in a Mathematics course, a prerequisite might be completing a lower-level math course.
Corequisites are courses that must be taken at the same time as another course. They are often related and complement each other, providing a more comprehensive learning experience. For instance, in a Biology course, a corequisite might be a lab session.
Advisories are recommendations or suggestions for students before taking a course, but they are not mandatory requirements. They serve as guidance to help students make informed decisions about their academic choices. An example of an advisory might be having a certain level of English proficiency before taking an advanced literature course.
