I did it this way. I started every skill by saying "I'm going to wash my hands" so that skill wouldn't be forgotten. Then, for instance, I would go "Hello Ms Smith, I'm Tracy, your CNA today. I am going to assist you to a wheelchair". Then I'd talk thru the steps as I did them, so I would remember. "Okay, I'm going to lock the wheels on your wheelchair. Now I'm going to assist you to sitting and make sure you have shoes on". When I was complete with the task, I would say "I wash my hands and am finished". As long as you study the skills (I did flash cards) it will come to you while you are in the test. Good luck!
