CNA skills videos

I'm taking my tests in three weeks and I want to watch videos to make sure I practise all the skills correctly. I'm not currently employed so I have to practise them at home on family. I developed tendonitis after I finished my CNA class, so working just wasn't an option (couldn't even move my arm more than three inches from my body). Anyway, I want to practise and watch videos daily and need to make sure the ones I watch perform them correctly. One last question-in the ones I've watched so far they have always only used one basin of water for cleaning skills (ie partial bedbath etc). Is that what you all have done or did you bring one basin in for soapy wash and one for rinse wash?
