I have practiced many Social Studies passages, and about a third of the time, I only miss one question, the second third, I miss around 4, and then the last third I miss a majority of the questions. I don't know why this happens--is it because I need to prep more, and the passages I do well are just a fluke, or is it because I just don't vibe well with those passages I miss a lot on or do I need to practice less so I don't overdo it?
