GED Calculator – Can You Use a Ti-30XS Calculator on the GED Test?

Many students ask us, “Can you use a calculator on the GED test?”
Yes. You can use a calculator on the GED Math test, and on parts of Science and Social Studies too.

What’s even better: the GED test allows you to use the TI-30XS, a scientific calculator. This means it has advanced capabilities that let you answer most GED questions without being “fluent” in complex math.

But here is the thing: people fail math because they don’t know it.

I’m serious: our TikTok video explaining this got 3 million views and over 400 comments, and a huge share of them said some version of the same thing: “Wait, you’re allowed to use a calculator on the GED?” Some flat-out didn’t believe it. Others are saying how hard the Math test is.

Why Is the TI-30XS Calculator a Big Thing?

The TI-30XS is built to handle exactly the kind of problems that trip people up on the GED, such as fractions, square roots, exponents, and order of operations. Things that take real math knowledge to solve by hand take a few button presses with this calculator.

Learn how to use it for these problems, and GED Math gets easier than anything you did in high school.

This is also why Math has the highest failure rate of the four GED subjects. Not because the content is impossible, but because most people don’t know this tool exists, so they’re doing everything the hard way. You’ll find countless stories of people retaking GED Math two, three, even seven times.

Can I Bring the TI-30XS to the Exam?

Yes, you can bring your own device or use the calculator built into the GED Math screen. You find it by clicking the “calculator” link in the top blue bar of the test page.

This link is visible for 40 of the GED math questions; only part 1, the first 5 questions, doesn’t allow you to use this calculator.

How Do I Learn How to Use the TI-30XS?

Buying the calculator or knowing where to find it doesn’t mean you’ll immediately know how to use it on the test. You should spend some time, a few days, getting familiar with the techniques and practicing GED-style problems.

You can try to do it yourself, or take the Onsego GED Math course, which shows you how to solve all GED math problems using the TI-30XS. Check what’s included here.

Do I Need to Buy the TI-30XS?

Technically, no. If you test online, the calculator is already built into the screen. You never have to spend a dollar.

But here’s the belief worth pushing back on: “I don’t need a calculator; I’ll just use the on-screen one on test day.” That’s true, and it’s also a mistake.

The on-screen version works exactly like the handheld one, but test day isn’t when you want to be learning where the buttons are. You’re already managing time pressure and nerves. Fumbling to find the fraction key or the pi button while the clock runs is how people lose points on questions they actually knew how to solve.

An $18 handheld device means you can practice on the exact tool you’ll use, whenever you want, without opening a test screen. A few days of hands-on practice is the difference between “I recognize this calculator” and “I know exactly which button solves this problem,” and that second one is what actually saves you time on test day.

If money’s tight, the on-screen version is genuinely fine. Just don’t wait until test day to touch it for the first time.

How Onsego Built a Course Around This Belief

A few years ago, Onsego’s CEO, Steve Gory, got a call from his sister-in-law. She works in entertainment, and one of her clients, a songwriter named Nina, had passed three of the four GED tests. Math was the one that wouldn’t budge. She’d tried four times.

Steve gave her access to Onsego’s courses. They worked through it over a few months, but motivation was hard to find. Math had nothing to do with her career, and she was busy.

Then Nina asked a simple question: “Why can’t you just show me how to use this calculator to solve the problems? I can learn how to use a machine.”

That reframed everything. Onsego had been teaching math when it should have been teaching students how to pass the math test, using a tool that’s fully legal on the exam. The real skill isn’t memorizing formulas. It’s knowing how to use the calculator that’s sitting right in front of you.

Steve showed Nina this approach, and something clicked. Two weeks of calculator-focused study felt achievable in a way years of math review never had.

She studied for about an hour a day. Took the GED Ready practice test, scored in the green zone, scheduled the real thing, and passed with 168 points.

Learn the Calculator, Not Just the Math

Onsego’s Math with TI-30XS course teaches you how to solve GED Math problems using the calculator, no math background required. It’s included in every Onsego plan, or you can buy it on its own.
