For US-based students, the results are promising. A comparison of undergraduate data indicates that US students enter college with lower math and physics scores as well as fewer physics classes than their counterparts overseas. By the time they graduate with computer science degrees, however, the US students score significantly better, coming about 0.76 standard deviations ahead of their international peers. There were no statistically significant difference among the students from other countries. The gap actually grows if students from elite universities are analyzed separately. (Students at these elite universities also outperformed their peers at lower-profile universities.)
