Before you start
- Every question has four answer choices and one best answer, like GED multiple-choice items. The real test also uses drag-and-drop, fill-in-the-blank, select-an-area and drop-down items; ours present the same skills as multiple choice. Each answer comes with an explanation, and calculations show each step.
- Some questions share a passage or table, shown beside the question (above it on phones), as in the real test’s question sets.
- Check each answer to see the explanation before moving on. Checked answers cannot be changed.
Original independent practice. Every question is written for practice from GED Testing Service’s published assessment targets; none are GED test questions. Not affiliated with or endorsed by GED Testing Service or the American Council on Education.
