I wish this was an option for my son who is currently a high school senior.
I know my cousins kids in Florida have the dual enrollment and her son is taking college courses at the community college and will have his Associates when he graduates from high school.
By the time they reach their senior year here ...they are taking electives and filler classes. They actually spread out their requirements for Social Studies and English so that they have to take them in their senior year..or frankly, I don't think the kids would bother to show up.
When I met with my son's counselor last year, I questioned his schedule for this year. She told me they really should offer Seniors a half day of school..that most of the kids are just filling up their schedules with things they don't need for graduation, but are required to be in school a certain amount of hours.
My son actually took "work experience" which means he's leaves school two classes early in order to go to work. Given that he has lunch for his last period, it puts him back home at 12:30 pm this year.

What a waste.
He's so bored with school. He took the last of his Regents exams last year..and he's basically waiting to finish up his English requirement to graduate.
Would have been nice if he could have gotten a jump on his college courses.
