I never assumed they did. However, that being obvious (not all schools alike), your GPA from high school or ACT test score really means diddly squat if you are going back to school 10 or 20 years after you graduated from High school. So, that being said, as previous posters mentioned, nursing school is tough and getting your pre-reqs done first does make more sense from a less stress, better grades (because of a smaller workload each semester) standpoint. And it gives you a good base of education to start on for nursing school too. Pretty sure they don't waste alot of time your first semester of nursing covering stuff like anatomy or chemistry that you SHOULD know from pre-reqs. They assume you know it and go from there.
