Can I get a grant for a ged, online and how

I don't know about grants for GED's but you can type cyber school and your county or city in the search engine to see if you can do cyber school and your local school district is suppose to pay for it (but if you dropped out I am not sure)
Worth checking into.

IF you are very low income, check with your case worker, they have programs to help you with getting your GED
