I was told its all about common sense I also posted a post here six times and no one ever help a person timer taking the CNA exam. On my previous post I mentioned, what do I need to study to prepare myself for the CNA exam? I'm just nervous what to study on all I know is the clinical part of the exam and the part with the writing my Prof. told me its just common sense which I'm too afraid of taking. The final exam I took from class I received an 80 ten more to get an 100 not good in my case. Does anyone know what should I study to prepare myself for the actual CNA exam?
