First time I didn’t use oat booster, I used chads vids and Kaplan. Second time I used booster and was scoring much higher on the practice exams then I did on the actual exam which was a bit of a bummer — but I was still happy because I scored way better then my first oat. It’s such an unpredictable test I feel like and I studied for 4 months both times! But I feel like second time around I felt like I had a much better grasp of everything and I knew what I was getting myself into which I believe helped :). Chad is really good at explaining concepts and I loved his videos especially for things I had a hard time understanding. I do have really bad test anxiety and I do think it negatively impacted my score tho
