No, I don't know where you heard that information, but it's not true at all. Employers don't care about how many years you've spent in your education, all they ever care about is whether or not you've got the degree or not. It doesn't matter if it's high school diploma or a college degree. You have to finish it and finish the entire program. Never do things and stop half-way, you need to complete it without flaws. If you've already got over high school, then I suggest you to go to college in order to get a higher degree. Employers are greedy, they only want the best people to work for them. If you have job experiences, then that's a plus.
