Could be. I have found that those GED students, and other students in adult basic education classes, are pretty serious about what they are doing and have definite practical reasons for going back to school. They grew up and found out the hard way that neglecting their education was a big mistake.
A young man I worked with dropped out of HS and immediately got his GED. He had a wide skill set. Although I was 3 times his age he was the manager and great.
