My empirical observation has been that home schooled students are invariably better prepared for learning at the collegiate level than students that went to public school. To a large extent this is because the former has not been afflicted by the damage perpetrated on the latter. Cognitive development involves both knowledge acquisition and development of reasoning formalism ( critical thinking, quantitative reasoning, etc.). However the focus of public education, at least in GA, has focused on passing standardized tests. Hence students are only taught material necessary to get through the test, not the content to any real depth; and certainly only at the lowest levels of Bloom's taxonomy. What is worse, they are indoctrinated into a faulty learning method of memorize, regurgitate, and forget. Believing that to be normal retards their willingness to accept substantially more effective methods of learning presented in college.
