Both the GED and SAT gauge where a student is academically, though the purpose of the tests can be quite different. If you're thinking about enrolling in college, you'll need to take one or both of the tests to demonstrate that you're a good candidate for higher education. Knowing the exact differences between the tests will help you determine which one will help you accomplish your goals.
The GED, or General Equivalency Diploma, includes a combination of academic subjects, such as math, literacy and science, that test you on you general understanding of each. Each of the questions on the GED test includes five possible answers, and your job is to choose the correct answer for each test. The SAT, or Scholastic Assessment Test, is a standardized test that most colleges require high school juniors or seniors to take before accepting them for admission.
