Science: What You Need to Know

The GED Science test has a 90% pass rate so you have a very good chance of succeeding if you have a basic understanding of scientific concepts. Luckily, the science test is not a memorization test. For example, you won’t need to memorize the periodic table of elements.

Test Topics

The Science section of the GED includes three different topics: 

  • Reading for Meaning in Science
  • Designing and Interpreting Science Experiments
  • Using Numbers and Graphics in Science



You’ll need to understand science concepts, know how to read graphs and charts displaying scientific data, and use reasoning to interpret science information.

Format of the Science Test

There is only one section on the GED Science test. It is 90 minutes long and there are no breaks. A calculator is allowed and a calculator reference sheet will be provided. 

There are also different question types including multiple choice, drag and drop, fill-in-the-blank, select an area and drop down. 

How to Prepare

There are many ways to prepare for the Science test. Start by logging in to your account and checking out our free study guide that will help familiarize you with what to expect on the test. 

Classes are also a great option, which are available in-person at an adult education center or online if getting to class isn’t an option. 

If you need more practice, GED Flash offers thousands of interactive practice questions that you can access anytime, anywhere. 

Lastly, once you’re feeling confident, take the official GED Ready practice test and know before you go take the real test! 



  1. Minor correction for you: under “Science: What You Need to Know”, the first sentence under How to Prepare says, “There are many ways to prepare for the Social Studies test.” I assume “Social Studies” should be replaced by “Science” in that sentence.

    1. Hi Hasan. You are able to attend university with a GED so you should be able to become a Bachelor of Science.

  3. Logging into your account and accessing a free study guide is a good starting point. Study guides often provide an overview of the topics covered on the test, key concepts, and sample questions. Make sure to thoroughly review the guide and take note of any areas where you feel less confident.
