I have just entered my 2nd semester of RN school. Our professors are telling us it is very important to get a job as a CNA while in school as most hospitals in our area (Maryland) are only hiring RN's from within their hospitals. That being said, I currently have my CNA license and have put out A LOT of applications but still don't have a job. My 1st semester of RN school was extremely tough. The material was not so hard, but I am extremely competitive and demand a lot from myself so I spent s lot of time studying. The studying paid off in the grades I received.
My humble suggestion for what its worth is that if your husband doesn't care one way or the other you may want to not work during this semester especially if you have children. Give yourself the time to focus on school and adjust to the demands it will place on you, and then try for a CNA position over the holiday break or over the summer.
Just my thoughts, will be interesting how more experienced students/RN's respond. Good luck with your schooling. Best decision I have ever made.
