Check with your local GED Testing Center regarding the number of times you can take a GED test within a year. Some testing centers will allow you to take each test up to three times within a calendar year.
You don't want to be caught off guard if you fail a test..... and then find out you need to wait awhile before you can retest.
Check first to see what the guidelines are for your area.
Stop in at your GED Tutoring Center or give someone a call.
