The program isn't like most schools. You don't actually get to choose what you're going to take. There are no extra classes aside of the ones needed for your degree. If you're looking to continue on for a BSN, you'll need to take some of those additional Science classes either at the school where you're going to get the BSN (recommended), or a community college, etc.
The schedule varies from class to class. Most of the time, lecture is about the same. It's rare to be in lecture past 3:00p.m. for any class, but it can happen. Clinical varies from teacher/facility. Generally, expect to be at the clinical site at 6-7a.m., and be there until 3:00p.m., at least. Other than that, each class is different in terms of what days clinical is on, lecture, etc. Some classes have it where you have a day off, which is nice. Others go every day.
Never apologize for asking questions! It is a very important decision, and you should definitely know what you're walking into. Don't worry about rushing into anything, really. I started back up when I was 26, I'm 29 now, and graduated (no regrets).
It is a good program. You'll have to bend to some teachers/classes, and go with the flow (as you'll see some indescrepencies here and there). However, as hard as the program is, it really does get you ready. We've more clinical hours than any other school in St. Louis (as far as I know), nearly 1,000 hours. Hospitals love that. From my graduating class (November, 2013), I haven't heard of anyone failing the NCLEX who took it yet, and everyone that passed, passed with 75 questions.
Before starting into any school/program, you need to sit down and ask yourself... what is it that you want in a career. If need be, try and see if you can follow a nurse for a couple of hours, and see what they do. You don't want to get half-way through the program and realize that this isn't what you wanted to do.
If you decide that nursing is what you want, I definitely recommend Lutheran, even more if you're looking for an accelerated program. Of course, I am biased since it's my alma mater. But I firmly believe that my school makes great nurses.
