Your comment is based on the presupposition that lower income kids have:<p>(1) An internet ready device.<p>(2) Reliable internet service.<p>(3) A quiet environment where they&#x27;re able to study undisturbed.<p>(4) Have the time available to study, no younger siblings to watch over, and don&#x27;t have a strenuous paid job.<p>For many lower income kids studying for the SAT isn&#x27;t practical, even if the material is available at no cost. Khan Academy certainly helps a lot of students that can&#x27;t afford expensive tutors or private classes, but it&#x27;s by no means a complete solution. We need to do more as a society to help disadvantaged students prepare for college.
