Is there a way that is cheap to graduate high school?

You mean, go back and get a GED? Or just finish high school in general?

You would need to contact your high school to find out their policy on returning, if that is what you mean.

If you mean the GED---no, there is no way to NOT pay for it.

Be very suspicious of online high schools. Most of them are NOT accredited, and NOT recognized by any state's department of Education---and are a complete waste of money because they are not valid.

Synnen is correct.

Go for quality before "quick". The purpose of going to school is to be educated, not just to graduate.

I am in the same positition. I was going to MECs it's a free night school but I believe after a certain age you have to pay for it. Google it. Mountain Education Center
