It definitely depends on the school. The program I'm in, I spent a full 12 months getting ready to apply. So, I took A&P I and II, microbio, statistics, nutrition, and pharmacology before I ever applied, and now I don't have to take them (or pay the more-expensive tuition for them) while I'm overwhelmed with clinicals! I "tested" out of a few things because I have a masters but never took a writing course, so did a CLEP exam for composition. But while my chosen strategy works for the school I'm attending, it's going to depend on each school's requirements. My advice is to ask their admissions rep or registrar. My school's registrar helped me tailor my coursework before I'd even applied. It was so helpful. You might consider asking them for a sample schedule (the schools I applied to all had one, and so I took any and all general-education/non-nursing-core courses on it), and for classes you think you can test out of you can ask them if they accept CLEP (clep.collegeboard.org).
