Can You Use a Calculator on the GED? Yes — When + Which One

Yes, the GED allows the on-screen TI-30XS scientific calculator on most of Math Part 2, plus Science and Social Studies questions that involve calculations. Part 1 of Math (first 5–6 questions) is calculator-free. You don't bring your own — the calculator is provided on-screen during the test. Familiarity with the TI-30XS pays off in time saved and errors avoided on test day.
