I understand your frustration but can you sit for the boards with the credit hours? If the answer is yes then keep going. The program I attend isn't accredited by ACEN, but it is approved by COE of my state and it's on my BON education list.
Don't let anything deter you from your goals and your dreams.
I gave up my CNA position to focus solely on my program. Some of my classmates work 16 hr shifts on the weekends and our off days. My LVN program is very rigorous I couldn't imagine working, but hey it's different for other people. I'm in my second semester. Good Luck.
