Question 1021194
New Math or Old Math, not much different for purposes of GED test in Mathematics.  Check with your local adult school.  The attendence office or counseling office will help you register for GED preparation course/courses.  There, either in the office or in the class, you should be assessed and given suitable instruction.  One option at the adult school is to try Pre-Algebra as a course, and then Algebra 1.  The Algebra 1 course should take care of much of the knowledge and skill necessary to handle GED Mathematics questions.
