(AP)-For the first time, more high school students are taking the ACT college entrance exam than its rival, the SAT. The College Board is releasing its scores for the high school class of 2012, which scored one point lower on average than the class of 2011 on the critical reading and writing sections of the 800-point exam, and the same on math. The non-profit membership group also disclosed a figure of 1.64 million test-takers last year, slightly lower than the ACT reported on its exam last month. The cross-over is no surprise. The ACT has been growing more rapidly in recent years because it is taken by virtually all students in nine states.
