Beware of programs that promise a diploma in a short period of time. Getting your GED in a few days or one week is unrealistic. Preparing for the test, gathering information from your local GED testing center, and then waiting for the test results will take a few weeks at the very least. Contact your local testing center to obtain practice testing materials. To find a testing center near you, use the GED Testing Center search feature from the American Council on Education website (see References).
Drop the GED program if it promises you better grades. This is a tell-tale sign the diploma you ultimately receive might be a fake. The only entity that can promise you a stellar grade on the GED is you.
Never take a GED test online. The one place where you are guaranteed to take an authentic, official GED test is at a GED testing center. More than likely, there is a local testing center near you. A GED test taken online is a scam.
Double-check the school's accreditation if you are taking a GED test from an online high school program. If you are also applying for college, check with the admissions staff to see if the college will accept a GED diploma from this program.
