I recently took my STNA test. Its pretty easy. They will split you up, one person goes and does the skills portion then one person gets put into a waiting room. Everyone else goes and takes the written part of the test. The skills portion everything is laid out for you so you don't have to remember every little thing you need in a skill. The tester will tell you the skill and you can ask them to repeat the skill requirements as many times as you need. You can repeat any skill that you think you did wrong in your time limit. It took me about 15 minutes to do all my skills.
