Let me add to the above.
NO judge anywhere in the US is going to emancipate a minor who is failing in school. NO judge anywhere in the US is going to emancipate a minor who does not have the means to pay all of her own support. No judge anywhere in the US will emancipate a minor based on what that minor claims they will do after they are emancipated, such as get a job or improve their grades. You need to have the job and the improved grades BEFORE emancipation will even be considered.
And that's if emancipation would do what you wanted it to. Which in your state, it won't.
