CNA re-competency testing

Hey all!!!

I took a CNA class and later went on to take a MA class as well, but haven't used either one in about 5 years! Anywho, I'm starting nursing school in August and if I have to either retake the CNA class or take a CNA re-competency test. I worked in a LTC facility for a year or so, so I feel like I'm pretty good with the skills but I'm a little nervous about being tested on it! Does anyone have any ideas on how I could brush up on information and skills? I have to take the written and the clinical test. Thanks!
