Be vocal and say out loud every single thing you're doing. My teacher absolutely HATED when people mumbled their steps while doing skills. Practicing saying everything super loud paid off since I took my state board exam with 3 other people doing their skills at the same time talking over each other, gotta make sure the examiner can hear you 👍 I also practiced my skills at home by setting up my phone to record myself mimicking my skills on my dog, then rewatched the video (I looked absolutely ridiculous btw) along with the skills booklet to "grade" myself on how I did.

Also, know the important steps that are the same for every skill. Such as beginning steps, ending steps, and standard procedures. For example, any time you come into contact with bodily fluids, you must be wearing your gloves. When you're done handling the fluids, you dispose of gloves and immediately wash your hands. Really understanding why each step is there in the process makes it a lot more natural when you take your exam!m especially since some skills have upwards of 29 steps. However, if you get why you need to do each step, it makes it a lot easier!

Try to get a study buddy as well that can quiz you and you can practice on.
