I'm having trouble improving my BS score. I've improved a total of only 2 points ever since I started studying for the MCAT, and somehow I can never get above an 11. I don't really make many stupid mistakes, it's just that most of the questions I miss are because I fail to make certain connections between the question and some piece of information in the passage or with a piece of outside knowledge. I do go over my answers (both right and wrong) and understand the reasoning afterwards, but I keep making the same type of mistakes over and over again. Any suggestions on how I can improve?
