GED Math Test Tips: How to Study and Prepare
Math gets easier when the foundations are stronger.
Math often needs a different kind of practice. Reading an explanation is a start, but solving problems yourself is where the learning sticks.
GED Math: Why You Need a Different Study Strategy
Math was by far my biggest struggle when studying for the GED. I spent more time preparing for this subject than any of the others.
One thing I learned is that you can't study math the same way you study Science, Social Studies, or Language Arts.
Math is different because so many of the concepts build on one another. You need to understand certain skills before you can move on to more difficult problems.
For example, if you don't understand negative numbers, fractions, or basic algebra, you're probably going to struggle when you get to equations, slope, and other advanced math problems.
This is where I made a mistake when I first started studying. I would come across something I didn't understand, get frustrated, and move on to the next lesson. But eventually, I would run into another problem that required the same skills I hadn't learned earlier.
With math, you have to build a foundation first.
What's on the GED Math Test?
The GED Mathematical Reasoning test is 115 minutes long and covers four main areas: basic math, geometry, basic algebra, and graphs and functions.
About 55% of the test focuses on algebraic problem-solving, while the remaining 45% covers quantitative problem-solving, including numbers, measurements, and geometry.
You'll have access to a math formula sheet, and a calculator is allowed for most questions. You don't have to memorize every formula, but you should practice using them before test day.
How I Recommend Studying for GED Math
Start with the Kaplan GED study guide, just as you would with the other subjects. But instead of rushing through the lessons, take your time with each new concept.
Here's the process I recommend:
Learn one concept at a time. Read the lesson in your Kaplan guide and work through the examples.
Use YouTube or AI when you're confused. If the explanation in the book doesn't make sense, find someone who explains it differently. Sometimes you just need to hear the same concept explained another way.
Practice that specific skill. Don't immediately jump into a bunch of mixed GED questions. Practice the type of problem you're learning until you can solve several on your own.
Make sure you understand it before moving on. You don't have to be perfect, but you should be able to solve most of the practice problems without needing to look at the instructions every time.
Review older skills regularly. Even after you've learned something, practice it occasionally so you don't forget it.
Once you've worked through the main math concepts in your Kaplan guide, start using GED Flash to practice mixed GED math questions.
GED Flash will help you identify the areas where you still need work. If you keep missing questions about the same topic, that's a sign you should return to that lesson and spend more time practicing it.
Don't Try to Memorize Every Math Problem
One of the biggest lessons I learned is that memorizing the steps to a particular problem isn't always enough.
The GED might ask you a similar question using different numbers or wording. If you only memorized the original problem, you might not know what to do.
Try to understand why you're taking each step.
And don't be afraid to ask ChatGPT to explain the same problem five different ways until something finally clicks.
Math takes patience, repetition, and practice.
You don't need to become a math expert to pass the GED. You just need to build enough understanding of the concepts you'll be tested on.
If math is your hardest subject, don't let it discourage you. Give yourself more time, work on one skill at a time, and remember that every concept you learn makes the next one a little easier.
The goal isn't to learn everything about math. The goal is to learn enough math to pass your GED.
Build Your Math Skills in the Right Order
Math is easier to understand when you have a strong foundation. Before jumping into algebra and more complicated problems, make sure you're comfortable with basic skills like fractions, decimals, percentages, and negative numbers. These concepts appear throughout the GED math test, and understanding them will make more advanced topics easier to learn.
Once you've mastered the basics, move on to equations, algebra, graphs, slope, and geometry. If you find yourself struggling with a particular topic, don't be afraid to go back and review earlier lessons. Sometimes a little extra practice with the fundamentals is all you need to make something finally click.
Learn the TI-30XS MultiView
If I could give you one piece of advice about preparing for the GED Math test, it would be this: Learn how to use the calculator!
This is something I cannot emphasize enough.
The GED Math test allows you to use a calculator for most of the questions. And I'm not talking about a basic calculator that just adds, subtracts, multiplies, and divides.
The calculator used on the GED is called the TI-30XS MultiView Scientific Calculator, and it can do much more than you might realize.
It can help you with fractions, negative numbers, exponents, square roots, and many other calculations you'll encounter on the test.
Learning how to use this calculator can save you time, prevent calculation mistakes, and make certain types of math problems much easier.
Here's What I Recommend
Start learning how to use the calculator at the same time you begin studying GED Math.
Don't wait until you've finished your lessons.
Whenever you learn a new math concept, find out whether the calculator can help you solve the problem.
For example, learn how to use it for:
Fractions and mixed numbers
Negative numbers
Exponents and square roots
Percentages and decimals
Calculations involving parentheses
Substituting numbers into formulas
Calculating slope when you're given two points
YouTube has plenty of tutorials specifically for the TI-30XS MultiView calculator. I recommend watching these videos and practicing the buttons yourself.
You can also use ChatGPT to walk you through exactly which buttons to press for a particular problem.
Should You Buy Your Own Calculator?
You don't have to purchase a calculator because the GED provides an onscreen version during the calculator portion of the test.
However, I recommend considering a physical TI-30XS MultiView calculator if you plan to take your GED at a testing center.
Having one at home allows you to practice with the same type of calculator you'll use on test day.
You can also bring an approved TI-30XS calculator to an in-person GED testing center.
If you're taking the GED online from home, you'll need to use the onscreen calculator instead.
Don't Forget the Non-Calculator Questions
There is one important thing you need to know.
You cannot use a calculator on the first part of the GED Math test.
This section tests basic mathematical skills, so you'll still need to know how to work with numbers without relying on a calculator.
Fortunately, the calculator-free portion is relatively small compared with the rest of the test.
Spend time practicing basic arithmetic, fractions, negative numbers, and simple algebra without a calculator.
Practice Using the Calculator Every Day
The last thing you want is to sit down for your GED test and waste valuable time figuring out which buttons to press.
Get comfortable using it before test day.
When you're working through Kaplan or GED Flash questions, practice using the calculator whenever it would be allowed on the actual test.
Remember, the calculator won't replace understanding math, but it can make the math you understand much easier to solve.
You don't have to do every calculation in your head or work out every problem by hand.
Learn the math, learn the calculator, and use them together.
It could make a huge difference in how confidently you approach the GED Math test.
A calculator is a tool, not a substitute for understanding. Learn what to enter, why it works, and how to check the result.
