Both BSN and ADN programs are excellent. The main thing I had to consider is how I was going to pay for college. Initially I was involved in a scholarship program with the hospital I worked in during high school and planned to get my BSN but the program lost funding so I had no way of paying for tuition to a four year school without being deeply in debt. I chose a community college with a good reputation that had rates I could afford. It was probably the best decision I ever made. The smaller class size and personal guidance made all the difference.
There are a lot of factors to consider when choosing a program and most do require pre-reqs. Mine took a year before the nursing part of things. I agree with Tweety about checking with the local forum. You will need to apply yourself regardlees of what program you choose. Good luck.
