Lately, during practice, I have noticed that I keep getting flaw questions wrong but I cannot identify exactly why. Every time I look at the ACs, I can think of a reason why a few of them could be the answer and struggle in choosing the best AC. Anyone struggling with this too and have any tips?

I am planning to take the June LSAT but lately I have been feeling really stressed. On practice LR sets I second guess myself during AC evaluation and sometimes take too long, but then during blind review I easily understand the question and chose the right AC. Additionally, I keep getting in my head about not maximizing my study time efficiently and not studying hard enough. Anyone else feeling the same? If so was there anything that helped you get out of your thoughts?
