Another good reason to take the class at a community college is that you'll be familiar with the equipment and it will be easier for you to pass the skills portion of the test. At ECTC, they do the skills testing for several other CNA classes. And, IMO, the examiner is far less like to fail "one of their own".
The class was pretty easy, though it did take a lot of my time. My class was 5 weeks long so it was 15 hours a week, plus about an hour or two before each class to complete the workbook. Other than doing the required workbook, I didn't study and got an A.
In case you're wondering, my CNA class cost $363 (tuition) plus $65 for the book and a bit less than $50 for a uniform
I haven't found a job yet as a CNA, but I haven't looked that hard. I have a $10.50/hr weekend-only job that won't interfere with school (starting LPN in a couple of weeks) so for now I'm keeping it. Most CNA jobs here start at about $8.50 from what I hear, so I'm in no hurry to take a pay cut.
