Im needing to no how to get my GED or High School Diploma online. What site should I check out

GEDs are handled locally. Call your nearest high school or community college.

Google "how to get my GED" and add your state, town, city, or county, and see if online classes are available.

You do not do GED online (and if you find a site that says they do, run) GED is handled by local offices of the state government, and done though the local schools and/or some non profit grounds that will offer the test and local classes.

Online high school, with the exception of some of the major schools are merely "home school" with a diploma and any that do not require a few years of classes are just worthless in reality.

You can homeschool online and get a diploma when you finish the required courses, but you cannot get a GED online. A GED is handled differently in every State, Province, country, etc. You'll have to find out what the requirements are where you live.
