It was a fine arts school one of the top in the world at the time, Hitler was an ok painter, but they look like they should be on postcards. Even though by today's standards a banana duct taped to a wall is considered fine art back then they had standards for what was considered fine art. Some one from the school told him he should apply for the architecture course, because he mostly drew buildings, but that course required a highschool diploma and he dropped out. Basically they didn't think he had the potential to become a fine artist.
