When a device uses a relatively obscure image format and a site that accepts uploads fumbles it, who is to blame? This is the question that came up when students couldn’t complete their AP college exams because of such a situation.
Students took pictures with their iOS devices of materials they submitted for the test. Their phones stored and uploaded the pictures in HEIC format. The College Board’s server didn’t recognize the format and timed out. The students immediately failed and were told they could retake the test in three weeks.
