Tense time for AP students: grade weighting flunks a test

Jay Matthews:

Like all human beings, educators accept rules and procedures that make sense to them, even when academic types wave data in their faces proving they are wrong. That appears to be the case with one of the most powerful and widespread practices in Washington area high schools—the extra grade point for college-level courses.
Thousands of students are taking panicked breaths wondering if what I am about to reveal will incinerate their grade point averages, keep them out of any college anyone has heard of and consign them to a life of begging for dollar bills like that scruffy guy on Lynn Street south of Key Bridge.
A new study shows that grade weighting for Advanced Placement courses is unnecessary. Schools have been promising students 3 grade points (usually given for a B) if they get a C in an AP course so they will not be frightened away by its college-level demands. It turns out, however, they will take AP with or without extra credit.
