I think if you did well in the pre-reqs especially the science courses it would go a long way in helping you get in. Bio, chem and microbiology in my opinion are the classes that might carry the most weight with adcom. The previous clinical experience is a def bonus. If you need to take an admissions test, make sure you rock it so it doesn't leave any questions regarding your ability. I had a 2.7 undergrad gpa. I spent time in ems, got A's on my pre-reqs and took the admissions test for nursing and scored in the 95% percentile. I ended up with ASN and BSN. I had a guidance counselor tell me I wouldn't get into a nursing program and should give up. I'm telling you, don't give up. Passed NCLEX on the first attempt at 75 questions and never looked back.
