CNA in Iowa, moving to Missouri. Help!

Hi! I am in the process of becoming a CNA in Iowa, but have decided to move to Missouri. I have already checked online and see that I can apply to challenge the MO certification exam without re-taking the class, but if I fail it once I have to take the class. I was hoping for some tips on the exam, what is it like? How difficult is it? The Missouri CNA class is more exstensive than Iowas and am afraid I will not pass the MO exam. I was also wondering if there are a lot of CNA oppurtunities in MO, specifically Kansas City area, and if it will be difficult for me to find a job being from Iowa without having any job experience yet.
Thank you in advance for any advice!
