CNA course

It's not difficult at all. It's mainly common sense more than anything. You can look up sample tests online from your state usually. The exam consists of a written test and a skills test. Like I said, it's not difficult at all.

Just curious, how much do CNA's in Texas?

This is for Texas...here's a couple of links that may be helpful.
