Personally I've experienced this recently, I was expelled from school as a junior in high school on February 2nd (Date isn't extra important, but it relates)
So i went 6 months through my junior year, only to become expelled from the school. If i were to choose to come back to school, I would've had to wait until August, and repeat my whole junior year again. I decided that wasn't exactly fair and i dropped out.
But In my perspective you basically are choosing:
Graduating high school = Easy work.
Dropping out = Harder work.
If you choose to drop out, be willing to work longer\harder to maintain a healthy living.
