Have you taken your PSATs?
Btw, dropping out means agreeing that your wages may be significantly lower than that of someone who graduates. But I'm sure you don't care about that, and it's all about opportunities and making your own.
Get a GED book and study for the test at a library or something. If you get a good score, I advise you to go on to a technical school to pursue whatever you want to do, or wait a while to figure everything out. It's always better to have a plan. I don't really know what I want to do, but I know I want to finish high school and go to a good university.
Driving test is easy, dw about that.
Good luck on everything
