Seniors and the handful of juniors who are in Mr. Dan DiRosa’s advanced placement civics class discuss their brutally long first quarter exam, which was taken last week and featured 170 questions (multiple choice answers) about the U.S. Constitution, federalism, and for good measure, some interesting political issues. A Jesuit alumnus (Class of 1981), Mr. DiRosa has been teaching social studies, including history and civics courses, for some 24 years at Carrollton and Banks. He admits, somewhat facetiously, that he took his own exam – and flunked. Mr. DiRosa would have passed the test only if he had curved the grades. That certainly explains, from his students’ perspective, Mr. DiRosa’s right-leaning civics with a curve posture.
