Highschool diploma > GED. However that is really only the case if you are stopping there. I finished highschool and recieved my diploma and have no intention of going to college, so a GED wouldn't be good for me. On the other hand you are intending to go to college and get your bach degree in computer engineering. I couldn't imagine a possible employer saying, wow this guy has a bach degree and straight A's all the way down, he aced his [insert comp engineering test], and I've heard he has an excellent attitude. But he did only get his GED, oh well.. next.

I don't see ^ happening at all. I say go for it.
