Hi, There is an ATI mobile app that you can download. It is called RN Mentor. I used this, it has so many practice questions with rationales and it helped me IMENSLEY for the predictor. It costs 20$ but its worth it. You can omit certain questions to focus on one area. Make sure you read the rationales on questions you get correct because the test questions on the predictor are the same material!! Some of the questions were exactly the same as the ones from the App. Good luck and I hope this helps!! I was able to score a level 3, and other classmates that bought the app also got level 2.
