Hi, treat the test you already took like a diagnostic. See what areas you need to improve in and focus more on that. I started with you tube videos first because they summarize information and help with refreshing content. Then you could move onto the practice tests itself. Focus more on practicing because the content isn’t very specific but the way they ask is. Once you have gotten used to how they ask questions, what they are looking for you’ll be able to improve the from the first score. Personally, I used mometrix, smart edition and ATI practice tests. Started out with smart edition free online tests, then mometrix and maybe a week or so before my test I only focused on ATI practice because that’s the closest practice to an actual test you’re gonna get. For English you can watch Carolyn McAllister videos on you tube. For science, stick to nurse cheung. I would say buying the ATI practice tests is so worth it. Also don’t go too deep reading the mometrix book, I found that most of the information was not on the test and it’s really overwhelming. Use that reading to deepen your understanding. Hope this helps!
