What they do is write a recommendation to the school district saying that I should pass. Then I take the logbook, portfolio, and recommendation to the school district. They proceed to tell me if I pass or fail for all my subject for the whole year. This is a pressure point. You don't know pressure until you have had this impressed upon you.
Most colleges think highly of homeschoolers.
I was over at Carnegie Mellon University and the admissions staff met with me. He said that most homeschoolers at CMU do very well. Because colleges look at grade as the basis of whether your in or out, and homeschoolers don't have grade, they put more emphasis on SAT scores, and other standardized testing scores. You need to get take many standardized test and do well on most of them. That way colleges will see that your doing very well.
