Failure rate for AP tests climbing

Greg Toppo & Jack Gillum:

The number of students taking Advanced Placement tests hit a record high last year, but the portion who fail the exams — particularly in the South — is rising as well, a USA TODAY analysis finds.
Students last year took a record 2.9 million exams through the AP program, which challenges high school students with college-level courses. Passing the exams (a score of 3 or higher on the point scale of 1 to 5) may earn students early college credits, depending on a college’s criteria.
