GED Testing Mathematics

Like the Language Arts, Writing test, the Mathematics test is divided into two parts, though they are not as distinct as the former's parts. The test's 50 questions, to which students have 90 minutes to respond, are divided in half, with the first half being calculator-optional.

The Mathematics test focuses on four main mathematical disciplines: numbers and operations (20-30%), measurement and data analysis (20-30%), algebra (20-30%), and geometry (20-30%). Approximately 20% of the test uses standard grids and coordinate plane; these questions are not multiple choice.

Common topics covered include circumference, square roots, ratios and proportions, the multiplying and dividing of vulgar fractions and decimals, volume, exponents, angles, and the Pythagorean theorem. Students must have at least a basic knowledge of both the American measurement system as well as the metric system in order to answer many questions.

Calculators are issued at the testing site, and no external calculators may be used. Scrap paper is also provided so students may work problems out using pen or pencil, though no paper may be taken out of the testing room after completion in order to prevent students from giving their answers to others who may not have taken the test yet. Students are also provided with a list of common formulas, though this is controversial because some critics consider this to be too much assistance for those taking the test.
