A) The test isn't likely to be very useful as a means of estimating students' future classroom performance.
B) The test publisher has made a mistake–such a number isn't mathematically possible.
C) The test is a mediocre predictor at best, but it appears to be a more accurate predictor than most scholastic aptitude tests on the market.
D) The test can provide a good estimate of low-achieving students' classroom performance, but it probably won't be very accurate for high achievers.
