Bill Gates is numero uno. it is nice knowing more about the champion of the champions. please develop some more quiz on Gate\'s innovative ideas that made him where he is now.
Unlike in India, law is not studied formally at the undergraduate level in the US. Students can take a loose set of courses dubbed "pre-law" to help prepare for law school after finishing their Bachelors but it is not a pre-requisite and is not offered as a major at Harvard ( http://webdocs.registrar.fas.harvard.edu/ugrad_handbook/current/ )
Gates went to Harvard for Computer Science and pre-law and had he finished, he would have most probably majored in Comp Sci. Poorly thought-out question.
