You may want to wait a bit until you are comfortable in your first job before you jump into the additional stress of a degree completion program. FYI, there's no "transformation" involved - you just have to complete all the additional requirements needed for the BSN. You would also have an opportunity to take advantage of any tuition reimbursement offered by your employer.
Look at the programs available through traditional nursing schools
. Most of them now have RN-BSN programs with most, if not all, classes online. They are a lot less expensive
than commercial (for profit) schools & your BSN diploma will look just the same as if you attended the traditional program. Basically, RN-BSN programs are structured for working students so it will be much more do-able than your ADN program.
I would suggest starting by having a conversation with counselors at your current school to see if they have any degree-completion agreements with 4 year schools. A lot of them do. This would mean that you won't have to go through a big song and dance to see how many of your credits will transfer because they have already worked that out through the agreement.
Best of luck to you. Keep us posted on your progress.
