Domande frequenti

Is this the official GED Science test?

No. This is an independent practice course. It is not run by GED Testing Service, and your scores here are not GED scores.

What does the certificate from this course show?

The certificate of completion shows that you finished this practice course and scored at least 80% on its final assessment. It is not a GED credential, not a high school equivalency and not an official score, so schools and employers will not accept it in place of the GED.

How long is the GED Science test?

It is 90 minutes long, in one section with no breaks.

What score do I need to pass GED Science?

You need 145 or higher on a scale of 100 to 200. To earn your high school equivalency, you need 145 or higher on all four GED subjects.

Do I need to memorize science formulas?

No. The official Science page says you do not need to memorize formulas; the information you need is provided. A calculator is allowed, and a calculator reference sheet is provided.

How do I sign up for the GED test?
