There is no valid solution for #2. Even for someone with a genius-level IQ and a desire to learn, making up for a few missed weeks of school is challenging. Making up a few months is basically impossible, especially if you're the type who was pre-disposed to drop out in the first place. With intensive one-on-one tutoring maybe, but that's not realistic budget-wise. And nobody is going to want to go back and be the 17-year-old in 9th grade with a bunch of 14-year-olds, because it's embarrassing (and if you think you can change the dynamic of teenagers teasing each other, good luck).
