I'm starting the traditional BSN program at UMass in the fall and it's going to take me 3 years. My courseload will be slightly lighter than if I didn't already have a degree but it will still be pretty full. I've been working on my pre-reqs for a year too. The accelerated programs are much quicker (14 -16 months) but from what I've heard they are extremely fast-paced. Good luck:)
