The regression toward the average phenomenon predicts that individuals who perform extremely well (or extremely poorly) on a particular task will tend to perform more toward the average on subsequent attempts. As Amy's first test score was well above her typical performance (B student), she should expect her second test score to regress toward the average, which in this case would be around an 85%.
