I was wondering if it puts me at a disadvantage when it comes to applying for CNA jobs.
I dont think it matters at all. All that matters is if you pass your state exam and get your license (go on state registry).
In your first week or two at your job you will learn a lot more than during clinicals. I felt prepared very well when I took classroom setting CNA course. Our instructor was an RN with about 25 years of experience and she knew exactly what state exams are. She taught us so well that everyone passed exams and skills portion with ease while students from other schools or colleges were at disadvantage and had to pay again to retake exams.
I think it is not hard to teach yourself the written exam. I know that there were PCAs that only had years of working experience. They could pass the written portion because most of it is common sense. But often they failed the skills exam because they developed poor habits.
Our state's skills exams were very strict. But we had plenty of in-class practice that it became a norm. We practiced all the skills on each other in the classroom with all proper steps as written in states book.
I think the hardest part is skills exam. You need to practice those somehow.
