The General Educational Development (GED) exam is a battery of five tests, and you earn your GED after receiving a passing score in all of the sections. The math section of the GED test is broken into two 45-minute segments: one to be completed with a calculator and the other without. Although there are two types of questions found in the math section, the answers are scored in only one way.
On 80 percent of the exam, you must answer multiple-choice questions. Each of the math sections will have 20 of this type of question, for a total of 40 questions. Each correct answer earns you one point. The points you earn from these questions will be added to the points you earn from the constructed-answer questions. This number is then converted to a standard score for the math section.
Twenty percent of the math section will require a constructed answer. Each part of the exam will contain 10 of this type of question. For these questions, you will be required to label points on a grid or fill in a blank. Each correctly plotted point or answer written in the blank will earn you one point.
After the total score for correct answers is converted to a standard score, you will get a number between 200 and 800. You must receive a score of 410 or higher in the math section of the GED exam to pass that section. To receive a GED certificate, you must pass all content areas with a score of higher than 410, and your combined score must total at least 2,250.
In addition to the standard score you will receive in each section, you will be given a percentile rank. This number allows you to compare your math section score with the performance score for graduating high school seniors. The higher the percentile, the better you did. For instance, if you received an 82 for your percentile rank, you outperformed 82 out of 100 high school seniors. This puts you in the top 18 percent.
