I truly think it depends on your financial situation, how much time your willing to invest, and personal choice. I'm a second degree student and initially my goal was to obtain a bsn. However, my finances are not allowing me to go this route. I just got accepted into an accelerated associate nursing program that last for 14 months, the cost is under 5,000. I already spotted a bridge program near me that will cost more less than 9,000. That's an estimated 15,000 for a bsn, you cant beat that. But, in my state like many, it is hard to get a job in the hospital as a new grad with an adn. Most hospitals prefer a bsn. So, I could possibly be forfeiting my opportunity to get into a hospital off the back. I personally don't mind, the numbers are too sweet to me. I plan on going back for my masters and I don't want to be in anymore debt. I already have accrued debt from my previous degree, vehicle, etc. Some absn and bsn programs can run you up to a 100,000k. On the flip side, an absn program can help you get to your goal quicker. It took me a year to do my pre reqs and I waited 2 years to get into an adn program, but thats because I moved out of state and application cycles was not matching up. In total it will have taken me almost 5 years to get a bsn. I think going the absn/bsn route at an affordable college is a great route for you. Lots of bsn programs allow you to just take upper division courses, if you have all pre reqs and a previous degree, which normally last for about 2 years.
Last but not least, don't put all your eggs in one basket. You stated you have a master, so I know your grades are up to par. However, nursing is a beast, depending on affordability and location of a school competition can get stiff. I've seen darn near 4.0 students get rejected. Think long and hard about it and see which route is best for you. Best of luck to you!
