Looks like it's the ACT's turn to have some problems. Apparently, a slew of students have had their scores thrown out because their testing center didn't start the exam on time. The reason for the late start time at a few of the schools, according to The Chicago Tribune: breakfast. The schools, in what I think is a nice gesture, are giving their students breakfast before the exam.
I remember plenty of times when standardized tests were started late. I distinctly remember hearing students in other classrooms taking breaks or leaving when my classroom was still in test-taking mode.
A lot of people in the east (where the ACT hasn't always been popular) have been talking about the ACT as a great alternative after some of the problems the SAT has had in the last few years. Looks like neither exam is exempt from issues.
