You can pass the GED Math test, even though it stops more people from getting their diploma than any other subject.
Math is the hardest of the 4 GED tests. That’s why Onsego built a complete GED Math prep around the TI-30XS calculator, the only calculator allowed on the test.
Get your GED Diploma Quickly
With Onsego, it’s simple and easy
That’s why Onsego created a TI-30XS calculator course, the only calculator allowed on the test.
In 2026, Onsego converted its TI-30XS calculator course into a complete GED Math prep,
Math with TI-30XS, giving students a full path to pass the math test using the calculator.
Instead of relearning formulas and concepts you’ll never use outside the test, you learn how to use the calculator to solve GED Math problems. No math background needed.
Here’s how it started.
A few years ago, Onsego CEO Steve Gory got a call from his sister-in-law. She works in the entertainment business, and her “friends” are often her artist clients. This time, she needed help for an upcoming songwriter named Nina.
Nina had passed 3 of the 4 GED tests but couldn’t pass Math. She had tried four times.
Steve gave Nina access to Onsego, and they had a few Zoom calls over the following months. Getting her motivated wasn’t easy. She had a busy life, and math had nothing to do with her career.
Then one day Nina asked: “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 question changed everything.
Steve realized Onsego was teaching math when it should have been teaching students how to pass the math test. The TI-30XS calculator is a legal tool on the test.
The real skill is knowing how to use it.
Onsego’s math tutors analyzed the GED Math test, identified the topics that appear most often, and built lessons around solving those problems with the calculator.
When Steve showed Nina the new approach, she was excited for the first time.
The idea that she could pass math by spending two weeks learning calculator shortcuts gave her real hope.
She studied 1 to 1.5 hours a day.
Then she took the GED Ready Math practice test and scored in the green zone. She scheduled her real test and scored 168 points.
She couldn’t believe it herself.
Since then, Onsego has helped many students like Nina who couldn’t pass GED Math the traditional way.
Math with TI-30XS is included in all Onsego plans. You can also buy it separately.
