All kids in America should drop out of school at 16 get their GED and then spend the last 2 years working and saving money.

Today in America the GED and Diploma are literally of equal value, you can apply to any job that doesn't require a college degree with just a GED including Government Jobs.

The optimal strategy therefor is simply to drop out after the 10th grade, complete the training in person or online and then take the test and take advantage of living with your parents.

They can't charge you rent, can't force you to buy your own food, they legally can not punish you financially in any way so find a job save up every penny in an interest earning checking account.

You'll earn between $31,200 AND $91,520 depending on the minimum wage. Not including tips above the minimum.

Once turning 18 you can either

a. Go to the local community college finish your general education

b. Stay with the same business and get an apartment

or

c. Apply to better paying job with your 2 years of experience.

11th and 12th grade are pointless because you 100% have already leaned all you need to and they give you no advantage for finishing.
