If a college freshman has missed learning something basic in public school, can't he just go online and teach himself using all the wonderful free educational math websites that homeschoolers like me use when they don't have a clue how to teach something?
That is possible, but remember that the student must fill in gaps while SIMULTANEOUSLY learning the new material presented. A freshman taking 4 or more courses, and adjusting to living away from home, may get discouraged or give up if he does not have the background that other students in his class have. I will try to ensure that my children are not in this category when they start college.
