pre-and co reqs?????

If a class requires a "coreq", you can take the coreq class WITH the class or before it. The prereq, you need to take it BEFORE it.

Pre requisites are things required prior to entry. For example, you must take either chemistry or intro to biology before you can anatomy and physiology. Thus making chemistry and intro to biology pre reqs.

Co reqs are things you can take with other courses. For example, you can take microbiology with your nursing courses at my school.

Another way you can view classes is as a class you can or have to taken concurrently. For instance, if you haven't taken algebra before intro to biology, then you must be taking precalculus with intro to biology as a co requisite.

For me, a co-req is anything that I would take in addition to the actual nursing classes during a semester. Eg. my school lists the curriculum in the first semester of nursing as: Intro to Pharmacology, Fundamentals of Nursing, and either Human Growth and Development, or Developmental Psychology. Because I do not want to have to take anything other than the nursing classes during the regular semester, I am taking those "extra" classes during the summer time. This summer I am taking Developmental Psych.

Coreq can be taken during the program, a prereq must be done before entering the program.
