You would have to find out which courses are required by the board. Years ago when I did the EC program (Regents) in MO, the board required Ethics & A &P with a lab. Wasn't a problem for me as I'd completed a year & a half of an ADN program & already had it. I went ahead & completed the BSN (one could do that at the time) due to the fact that I had been in an accident in the middle of the semester of the ADN program locally & couldn't finish the semester. Even though I had great grades, the waiting period to get back in was a year so I went the EC route.
I've never regretted it & would highly recommend EC but be careful if you want to work in CA, KS (& there may be other states- back then it was only IL that wouldn't take them but you could endorse after 2 years).
