I tutored basic math, algebra and geometry (plus English and science) for a while. All my students, with the exception of one, were adult GED seekers who had lost their jobs when factories closed. Some of them just could not understand no matter how hard they tried. I will say that no matter how hard they found what they were trying to learn, not a single one of them ever would admit defeat. They all kept trying.
