I am in the same boat as you, looking at the step up program at Kaplan. Here is what I do know.
1. Reg price for the ASN is 57K, with an LVN the cost is 45K if you do not have any classes to transfer in with.
2. ASN program is 24 months, step up is 20 months ( I'm not sure why it only gives LVN's 4 months off the course, but I believe the class load may be less than the ASN students) plus this includes your A and P 1-2 and Micro.
3. You must score a min. of a 24 on the Wonderlic SLE and there is also a KTP (Kaplan Test Prep) that you must pass. The min scores are 61% in the math section and 64% in the English comp/Reading section.
4. The next term starts in January with a deadline of December 10th, to have everything in and finished, if not, May 16th is the next term.
I hope this helps, it is all the information that I have at this time. Best of luck to you
