Free Online GED Science Test Preparation

One of my GED Scholarship recipients took the test and didn’t pass the science test.  She was determined  to pass, wanted to be part of the GED graduation in June, and has specific classes picked out for this summer to learn how to work in a dental or medical office.  Her dedication inspired me to do some research for additional online resources to support her self-study:

Find GED Science Test preparation books at

Before you use these links, a warning: At these sites don’t give away your email address, sign up for any accounts or contests, or click links for ads.  They are free website because they post advertisements or sell GED materials, and most of the ads are selling fake diplomas, overpriced courses, or degrees you don’t need yet.  Focus on the lessons and don’t get distracted.  Consider the ads like someone talking really loudly on the sidewalk outside the window while you’re taking the GED test.  Don’t waste your time even looking at them!

Some helpful study materials online:
  • McGraw Hill’s GED Science Student Center: Click a chapter, and you will see links on the left-hand side of the page for Chapter Outline with definitions to learn, online flashcards to practice. AFTER you have studied the chapter outline and flashcards, do the chapter review quiz, and GED practice quiz: give yourself 15 minutes for each quiz. Note: This is a companion to the McGraw Hill GED Science book that you can purchase at Amazon (I recommend you get it used: save some $ and the planet).
  • McGraw Hill’s Science Vocabulary to Memorize You can practice flashcards online, but I recommend writing them down yourself to help you remember better–you can use index cards or scrap paper cut in four pieces.
  • GED for Free’s GED Science Prep Lessons (note: you do NOT need to “sign up” to view the lessons)

Here are a few links for FREE online GED practice tests.  To time yourself online at the library you can go to this Online Stopwatch, click “Count Down” and set the timer for 10-30 minutes per test.  To figure out the amount of time, look at the number of questions and multiply it by 1.5: for example, 10 questions x 1.5 = 15 minutes, or 20 questions x 1.5 = 30 minutes:

Here are some good tips on:
I also recommend you read some science topics and take notes you can review any time at home.  If you make a habit of reading your notes, rewriting notes, or using vocab flashcards for 15-30 minutes per day for 40 days, you will be very ready.  Pick the same time of day, set an alarm on your cell phone, or tape a note to the milk in the fridge…anything to remind you to study EVERY day.  Not only will you be ready for the test, you will have practiced a study skill you can use to learn for the rest of your life!
If you come across science terms you don’t recognize, search in  You can get a decent dictionary at the local Dollar store, but look for a “College edition.”  If you have a question or want a concrete example of something use good old Google or your search engine of choice.  For example, from McGraw Hill’s GED Science Student Center, Chapter One, Chapter Outline, I wanted to know “What is an example of equilibrium in everyday life?” The first search response on Google was this blog post on Equilibrium in Everyday Life with examples like a toaster, seesaw, walking, fish, etc.  It included a few more science terms you might want to look up like fulcrum and V3 neurons, but I learned something new from it, too!
Don’t pressure yourself to read all the lessons and learn all the vocabulary and topics to pass.  To keep you motivated, focus on one thing at a time that interests you.  Use the dictionary, draw pictures, re-read the passage, and search for additional information online until you feel like you know that topic well enough to teach it to someone else.  Pretend that instead of studying, you are creating a lesson to teach to your niece or nephew or to train a new person at work.  Rewrite it in a way to be able to explain it to someone else.  But as soon as you find yourself hearing your cell phone timer go off because it’s study time, and you say, “I don’t really want to,” then switch to a new topic and say, “I’m going to learn something new today that will help me pass the GED test!”  Or reward yourself after 15 minutes studying with chocolate or a hot bath…whatever it takes to keep yourself motivated.
You can do this!!!!!
