It's intense. The program is split into six 8-week sessions. The first four sessions run from the second week in May to the middle of December; in that 6-month span, the longest break you get is 4 days at Thanksgiving. It's absolutely grueling, especially towards the end of that stretch. If you can make it to Christmas break, though, you'll be fine - I don't think we lost anyone after that point, or if we did, it was only a couple.
The program is definitely hard - our 40% dropout/failure rate speaks to that. Many people failed out, but some chose to leave because the program was too intense. A couple dropped into the traditional 4-year program or the 2-year "slow" accelerated program.
I think not working is a good idea. There were definitely people who worked a few shifts a month as techs/CAs/etc., but not many. They had also already been in those jobs for awhile so they weren't taking on a new job in addition to school. If you've never worked as a tech or CA, I would recommend it. I did not and I wish I had. There are so many little things you pick up just working in the hospital environment that I had to learn in clinicals (and am still learning during my orientation now!).
I will say this - if you are planning to stay in the Louisville area, having a BSN from Bellarmine will make you very marketable. I had 3 interviews by early March of this year and a job offer by the end of March in the specialty that I wanted. Many people had jobs before graduation or within a month of graduating. Being an accel grad alone is enough to get you an interview at several of the hospitals here.
Good luck! Feel free to send me a PM if you want, too.
