GED® Math Review: Arithmetic and Geometry (Volume 1)
A thorough GED® Mathematical Reasoning review of the foundational half of the test: number sense, integer and rational-number operations, fractions, decimals, percents, ratios, rates, proportions, unit conversion, measurement, and plane and solid geometry (perimeter, area, surface area, volume, and the Pythagorean theorem). Each lesson builds concept by concept, with worked examples and quick-check questions. The 46-question MCQ set covers every topic at three difficulty levels so you can identify gaps and drill exactly what you need.
