I've always had difficulties in mathematics throughout my academic career but I've now noticed a phenomenon which might be a bit strange and I was wondering if others could help me out with it. I'll work on math GRE problems and it becomes almost impossible to focus. I'll work on the problems but as I'm doing it, half of my brain is going over other things that have transpired throughout the day, as though I'll replay events or comments that have occurred. It becomes almost impossible to engage with whatever problem I am on and so therefore I end up making crucial mistakes. It's crucial to mention that I am not being distracted, as it were, but rather that I am almost doing two things at the same time, somewhat involuntarily. One part of is doing the problem, manipulating the symbols, establishing formulas, doing the necessary calculations even as I am scrutinizing, analyzing and critically assessing some topic or event that had transpired during the day 1. Does anybody else experience this phenomenon wherein you will be working on solving some problem while a part of your brain is engaged in some other tasks or activity and the two are simultaneously working together? 2. If so, what advice would you give me to become more fully engaged in the problems I'm doing? What mental/math hack would you recommend? How could I go about becoming less led astray by this?
