I am in MIchigan, I am about to take the Certified Nurse Assistant Test....?

Please tell me a site where they have all the skills broke down 1 by 1. I already check on youtube for videos to re-familiarize myself for the test. I finished my class in April so I need to refresh myself. I already have the practice test for the written part but I need the breakdown of the skills and any tips for those in MI that have took the test. I am taking my test at Wayne Community College. I was an aide before but I hear they are even more stricter now and I cant afford to keep taking the test paying that money. Thanbk you in advance.
