I also am not an RN yet but I am a CNA, and I think it is good for you to take these classes first, because not only does it help you out with certain things in the future but when you become an RN it will help you to realize what type of work the CNA's actually do and you will have more respect for them. I have seen RN's who never were a CNA, and didnt understand just how hard of work it is therefore they weren't very nice, if you get my drift, so I think its good to be a CNA first... just my opinion...
