How to Pass the GED Science Test – 10 Practical Tips

You need to pass four tests to get your GED diploma. Science is one of them.

Good news? Many students find Science easier than Math. But you still need to prep for it. The test throws passages at you, plus experiments, graphs, and chemistry/physics questions.

Don’t worry. With smart prep, you can nail it on your first try. At Onsego, our GED Science course (part of the Advantage Plan) has everything you need. Studying solo? These 10 tips will get you there.

1. Read the GED Science Questions First

Skip the long passages for now. Read the question first. This tells you exactly what to hunt for.

When you go back to read, you’ll only need the parts that matter. No starting over.

Stuck for more than a minute? Guess, flag it, move on. You can circle back later.

2. Use What You’re Given

Every question gives you something—a graph, chart, diagram, or passage. That’s your free hint.

Even if the topic is totally new to you, the answer is usually hiding in there somewhere.

Also, use that on-screen calculator. Even for easy math. Why risk a silly mistake?

3. Eliminate Wrong Answers First

Can’t spot the right answer? No problem. Cross out the ones you know are wrong.

Getting it down to two choices? Your odds just got way better.

4. Focus on the Big Picture

The GED Science test cares about concepts, not tiny details. You don’t need to memorize every biology fact. The important stuff shows up in the question.

Think big ideas, not random trivia.

5. Pace Yourself

You get 90 minutes. That’s it. Practice managing your time so one tricky question doesn’t eat up everything.

Here’s the thing—there’s no penalty for guessing. Answer every single question, even if you’re totally unsure.

6. Understand the Process, Don’t Just Memorize

Science on the GED is about applying what you know. Just memorizing terms won’t cut it. You need to get the why behind stuff.

Don’t just memorize the water cycle. Understand why it actually works.

Onsego’s video lessons show you how science concepts work instead of just listing facts.

7. Get Comfortable with Math Formulas

Some formulas are provided on the test. But you still need practice using them.

Don’t just memorize—actually use them in practice questions until they feel natural.

8. Know Scientific Variables

You need to understand independent and dependent variables.

Independent = what you change in an experiment Dependent = what you measure

Testing fertilizer on plants? Fertilizer amount = independent. Plant growth = dependent.

9. Look for Trends in Data

Graphs and tables pop up a lot. Don’t get lost in every single number. Look for the big pattern instead.

Most of the time, spotting the trend is all you need.

10. Use the Highlight Tool Wisely

The computer test has a highlighting tool. But don’t go crazy with it—it eats up time.

Many students find scratch paper faster. Only highlight if it actually helps you.

Final Thoughts

Passing the GED Science test is about smart prep, not memorizing everything under the sun. Focus on understanding concepts, practice with real test questions, and watch your time on test day.
