Not sure what to do...

Hi everyone, I'm looking for a little help. I completed a Red Cross Chha/CNA course, which included a week of Skill testing & a week of clinical. At the end we had two written exams....It was my understanding, that at the completion I would be certified. What i found out is now I must take a state exam...has anyone else encountered this? I thought for 800 dollars and four --forty hour weeks, I'd have something to show for it in the end. One more question, If I must take a State exam, does it have to be for Mass or can I take it in NH to be a LNA? Thank you for any info..
