I wouldn't drop out of high school, I'm not sure what its like in France, but here most high school drop outs don't have jobs. Some do get there GED. Is there a GED program of some sort in France? Here in the USA if your a certain age, you may possibly have to get parental signature or other requirements, you can take a series of subject tests, get a certain score, you have your GED. With that being said though the GED is said to be equivalent to the high school diploma but it is looked down upon by many people and of course employers. I hope you really figure out what you want to do and it doesn't cause you too much duress. Good luck!
