Greenville Tech accepts 30 students 7 times per year, I believe. I know that if you're unsure about having enough points to get into ADN program, you can apply to LPN program and get in that way. They accept 25% of students from LPN applicants, and 75% from ADN applicants. That's how I plan to get in.
Greenville Technical College has no wait list, but has a weighted admission process. It is based entirely on grades. The more pre-requisites you have completed and the better your grades in those classes, the better your chances for getting in.
