You could check if on-line CNA courses are allowed in your state. An on-line course would allow you to work full time while you learn. In my opinion, starting as a CNA is a good idea if you've envisaged becoming a RN later on. There are special CNA to RN bridge programs that will let you use your CNA credits towards your RN certification. You’ll find these programs online, at your local community college, or you can take things one step further, and do your RN studies at a 4-year university. No matter which option you choose, though, you’ll be able to cut down dramatically on your study time by being a licensed CNA first.

Like JustBeachyNurse said, it can vary; it depends on the state you're living. Therefore, it's always advisable to check with the appropriate authority if they allow to challenge the CNA exam after completing successfully your fundamental training. The CNA exam (a written examination and a skills evaluation) is not that difficult to pass.
