I think if homeschooling is done properly it can be alright...
I had a friend who joined our school halfway through year nine (I started year 9 when I was 13 so not sure what grade that is) and she had been homeschooled...
She got picked on, she had no social skills and neither did her sister, and when it came to education about a certain birds and the bees subject she freaked out because her parents were so strict and embarrassed about it she wasn't exactly in the know. She was really intelligent in other subjects, and eventually made friends but her social skills weren't ever really...all there. Theres a guy i'm still good friends with, he was homeschooled all the way to college (up til he was 16) and he's an absolute legend. Very intelligent.
My brother had to be homeschooled for a short while (long story) and my mum tried it. He eventually went to two more mainstream schools and then a residential school for boys with Aspergers. When he went to mainstream schools, kids just didn't want to socialise with him, they wanted to push his button so he'd react and then get in trouble. He then just wanted to go back to homeschool.
