Math Basics for a GED
Even if you score perfect 800s on the other four sections of the GED, you need to obtain a decent score in math to pass the test. While you need to average at least 450 points over the five sections of the GED, you must not score lower than 410 in any of the sections. Knowing what you are going to face on the test and studying accordingly can help you succeed in passing the GED.
