I took my certification test in March of this year (in Oklahoma). The only thing I found stressful (at the time) was doing the skills session in front of the tester. But she turned out to be super sweet and was very patient with me. The person I brought as my 'patient' was my husband and I couldn't for the life of me find his pulse! She did agree (probably placating me, ha) and allowed me to use her. They really do want you to pass (I believe).

The computer test was a breeze (for me). I got a 90-something.

I'm now in LPN school and also have just been hired by my local hospital using my CNA cert.
