I need to get a high school diploma

YOU need to take classes and get a GED... your local library might be able to point you to resources available in your area.

Should have stayed in school when you had the chance. Shouldn't you? Going to be far harder now... depending on how long its been. The longer since you dropped out the harder its going to be because you will have forgotten certain things.

STAT! Enroll in a GED class and go through the process. Expect it to take 40 hours or more or longer depending on if you pass the courses or not.

You can't get one "stat"...you need to go through the process of either school or a GED program.

There is no such thing as one without work. There are fake web sites that will sell you one, but they are not worth the paper they are printed on.

You either enroll in real school. Or go get a GED. It will take work and effort
