When I read the question stem, stimuli and organize information in my head and paper and look through the answer choices, at least 1:20 minutes has passed and it ultimately takes about 2 minutes to pick the answer. What are some tips I can get quick?

In the study plan, it is recommended to add a note for my wrong answer journal. Although I understand what I got wrong and why I got it wrong in my head, I'm not exactly sure how to summarize the note. Can anyone share how you add your own note for wrong answers?
