LR Content

Prior to PSA while going through the content I was fairly confident in my try it yourself question answers and was getting them right a high percentage of the time. However since SA I have been struggling on these questions and am getting fairly easy questions wrong. I realize that I am also unable to identify wrong answers as easily as the previous questions types and just wanted to ask if anyone had any tips on how I could do better on SA, NA, AP, MoR, and Flaw.
