Burn out/ information fog

Hello, this is my first time posting on a Reddit page, so please forgive me if I make any mistakes. I have struggled with taking financial exams my entire life due to severe dyslexia and ADHD, which has made the experience one of the worst of my life. I plan on taking the Series 66 in two weeks. I took it for the first time and received a score of 69. I’m currently using Kaplan and have completed about 2,500 QBank questions, but I find that as I focus on specific topics, I start to get confused about the broader concepts. Any advice would be greatly appreciated!
