I'd turn him away for being indecisive.
Agree. When my son was applying, we lived in California and the money was tight (money is ALWAYS tight in California, except for the rich people). It was $65 to apply, so I had to limit him to 5 schools. And he had full ride scholarship offers to several schools, including Berkeley, and UCLA. But two of the 3 Ivys rejected him and the third to which he applied wait listed him. It was $65 15 years ago......I cannot imagine how much it costs to apply now.
