A BUG IN THE SYSTEM: Remember 2014, when reports revealed that three states--Mississippi, Montana, and Wyoming--had no girls take the 2013 A.P. Computer Science exam? Looks like there have been a few improvements, but for the most part, there's still a lack in minority and female representation in a number of states. EdWeek reports that once again, Montana and Wyoming both had zero female students take the exam, while Mississippi and North Dakota both had only one. Furthermore, among the 49 states in which at least one student took the A.P. exam, 12 had zero black students participate this year--up from 11 states the previous year.
