I dropped out of school in 7th grade I wanna go back but would I have to go back to the 7th grade?

Forget it. Take classes at the community college, get an afternoon job, and get started on a life. Take acting and public speaking. Get "Dress For Success" by John Molloy and consider all the advice for students. (About the clothes: he doesn't say expensive clothes.)
- Vocal skill will affect your earning power more than any other detail.
- Acting skill will get you a job offer even when you are not qualified for the job.
- The most important benefit you get from school is your address book.
- The difference between a successful person and a very successful person is that the latter knows hundreds more people, and knows them quite well.
- No school will teach you any of the above. They don't even teach how to do well in their school.

Get a reliable job and a cheap pad within walking distance. No car. Save half your income. If you earn ten bux an hour and save half, in ten years you will have a hundred thousand bux. No other plan can give a positive net worth in only ten years. Study investments at the library in the evenings. At first you don't know anything about investing so buy pure silver coins and hide them at home. After the collapse (the nation is collapsing) the money will be no good but you will have precious metals to finance your investments.
