I am about to be a senior in high school, I live in Missouri, I am taking a program through my highs school called summit tech where I spend half a day at a nursing facility earning college credit for nursing programs, getting your CNA is an option there for $450, would it be worth it to obtain my CNA if I plan on going to nursing school to become an RN, or will it just be a waste of time and stress? Thanks Thank you guys!
