To succeed on the GED Science test, you will need to be able to read complex texts, identify precise details, determine cause and effect, understand science content, and identify evidence to support inferences and draw conclusions.

The Science Test includes a lot of charts and graphs that you will need to interpret, too. On the other hand, you shouldn’t worry too much about unknown Science terms. If you can think logically, you’ll figure that out.

To complete all GED Science questions, you will have 90 minutes. The  GED Science test does NOT include Short Answer items anymore.

You don’t need to know all sorts of details because all the detailed information needed to answer the questions is provided in the stimulus that comes with the questions.

To be successful on the GED® Science test, you should be able to understand basic science concepts and demonstrate knowledge of how scientific systems work.

There’s no need to memorize details. All the detailed information you need for answering the science questions is provided. However, you should understand the big-picture concepts and have a basic knowledge of how systems work.

These lessons are aligned with the Common Core Standards for Science. The Common Core Standards represent the next generation of K–12 standards designed to prepare all students for success in college and careers. These standards are the foundation of the GED test.
