How many schools have been built by Greg Mortenson?

The exact number of schools built by Greg Mortenson through the Central Asia Institute (CAI) is disputed. While Mortenson's book *Three Cups of Tea* claimed hundreds of schools, investigative journalism and subsequent audits revealed a significantly lower number, and significant questions about the accuracy of his accounts. There's no universally agreed-upon number, and the true figure remains uncertain due to the controversies surrounding CAI's activities.
