I was homeschooled 7th through 12th My parents had an extremely laissez faire approach. I picked out my own school books, studied what I felt like studying and ignored the rest. Can't remember them ever grading anything or checking to see how or what I was studying.
I thought home schooled people had to somehow prove that they had learned the required subjects. Tests or whatever.
That thing was definitely a winner of the "saying something obvious and making it sound like science" award.
