answer:Some universities don’t recognize a GED and they like students to have credit and high grades in specific diploma classes. Like Math, English and Science… The one I wanted to go to needed five five credit classes at a minimum grade level… So I went first to Business school and I found out the I needed Grade 12 English, Math, and two five credit classes in Sciences. So I retook all of my High School classes and Got a High School Diploma and then eventually made it to a private university with a C average. I need to get a Higher Higher School average of 70 – 90% and pass Physics and Chemistry in order to take any Science classes in the university that I want to go to. After 10 years I still don’t have the marks and I am learning on my own by purchasing my books on my own. As to the content of the course material I think they use the same textbooks.
