Yikes, $18,000 for tuition fees alone? I live in Finland where public education itself is free (well, payed from tax money, nothing is free after all) so it's quite incomprehensible for me to hear about these massive amounts it takes just to learn things - education should be human right, despite one's financial capabilities!

Also, we have free or very cheap lunch here.

Doing 8 hours of school and only getting 1 hour of learning out of it.

Eight hours is definitely too much for studying in a day, especially for your age. Even when I was in high school, my longest day wouldn't usually be longer than 6 hours consisting of four 75 minute classes. Even adults can't usually do more than few hours of deep work, so it's ridiculous to demand that from children. Absorbing information takes a lot of attention and that attention can be held only so long until performance starts to drop radically. It would be best to learn intensily for a short period and then rest (sleep) well - that is when the new knowledge gets internalized.
