Bill Gates scored 1590 out of 1600 on his SAT, was accepted to Harvard, excelled in his computer classes and had a definite plan when he left college.

But more to the point seem you were unable to answer your own question..

From the Bill and Melinda Gates Foundation :

A college education is the gateway to the American middle class, with college graduates earning as much as 65 percent more than those with only a high school education. But many who want to attend college cannot afford it.

Poor college completion rates in the U.S. hurt the national economy. Our investments seek to accelerate efforts already under way in higher education and to support the enormous talent, creativity, and energy being applied to improving student completion rates and lowering costs while raising the quality of the U.S. postsecondary education system.

So now you tell me, what does Bill Gates think about not completing college?
