One math test, about 46 questions in 115 minutes. Questions are multiple choice, drag-and-drop, fill-in-the-blank, and dropdowns.
An on-screen TI-30XS calculator is allowed on most questions. The first few questions must be done without it, so practice mental math too.
You get a formula sheet with area, volume, slope, the quadratic formula, and interest. You don't need to memorize those — just know how to use them.
Each GED test is scored from 100 to 200. You need a 145 to pass.
