I'm a single father I really want to get my high school diploma online I need help with a grant to pay for my schooling and books,supplies where can I find something like this please someone help

There is nothing, also be very very careful, there are almost NO, accredited high schools online. ABEKA is an accredited home school program, as is Seton but most are merely unaccredited schools.

If they are not accredited with the US Dept of Education, they are not

If you are in the U.S. check with the local high school district in your area. They should be able to help guide you to reputable coursework to complete your diploma.
