This is a debate that potiential nursing students have all the time. As a general rule of thumb, most people will tell you to do the BSN program if your pocket can allow it. Having a BSN in the economy can give you a slight leg up when looking for a job after you graduate. So i understand that thinking. However, I worked and paid my way thought NS and had to do the ADN first. It was cheaper, closer, and I liked the idea of working sooner.
Bottom line, you have to soul search and figure out what the best plan is for you and your life. You have all the tools you need. As a general rule of thumb, I tell people to do the "sure thing". Are you accepted into a BSN program? If so, do that one! Nursing schools are so competitive (if you search on this site, you will see PLENTY of people wishing they could get into school), so dont pass up the opportunity if you are already accepted.
Good luck! It's a tough decision, yes, but just be happy with whatever you decide! It's good to have choices these days!
