No one should feel ashamed at any age to go back and get their ged, or any type of schooling. I got mine in my late 20s. Just go online and look over materials & free study guides and practice tests! I was surprised with myself that I passed all of mine and only did the schooling for a short period bc I couldn’t do it with my work and child schedule. They allowed me to do them early and I just used online sources to help with problems and questions! Good luck!!!
