Country singer Gretchen Wilson has returned to school to complete the education she never finished as a child. The 33-year-old regrets dropping out of school at 15, completing only the eighth grade, and is now preparing to take a General Educational Development Test by the end of the summer (07). She says, "All my life, I just felt that I should have finished my education. I felt like I was missing something - that there was stuff other people know that I don't. And I want to know it, even if I don't need it." And Wilson is also inspired to learn so she can help her six-year-old daughter Grace with her homework. She adds, "When gets to that point and has trouble with algebra, I want to be able to say, 'Let Mommy help you.' I don't want to be ignorant in my daughter's eyes."
