May 06, 2026 – Onsego’s new GED math course teaches students to use the TI-30XS calculator, the tool already allowed on most of the test, to solve problems step by step.
MIAMI, FL, UNITED STATES, May 6, 2026 – Onsego, a GED Testing Service–recognized publisher of online GED prep courses, today launched its TI-30XS Math Course, a full GED math program built around the calculator the test already allows: https://onsego.com/math-ged-program/
The TI-30XS is permitted on nearly 90 percent of the GED math test. Onsego’s course teaches students how to use it on real test-style questions, step by step, so they spend less time stuck on calculations and more time understanding what the question is actually asking.

How the Course Works
Each lesson walks students through a GED math problem using the TI-30XS as the primary tool. Students learn to enter expressions, work with fractions, and test answer choices directly on the calculator.
The course focuses on three things:
Breaking problems into clear, repeatable steps
Using the calculator to reduce calculation errors
Identifying correct answers by working through options when the math is unfamiliar
“We see students gain confidence quickly when they realize they don’t have to do everything in their head,” said Steve Gory, CEO of Onsego. “The calculator becomes a tool they can rely on, not something they’re unsure how to use.”
