This is a reasonable opinion. Alternately, CB should write questions that are less CAS hackable. These would probably not be Common Core math questions.
And would you allow CAS for SAT Subject Test in Math Level 2 and AP Calculus? CAS is an even bigger help for those. If CB ruled out CAS for those tests, students might be angry. Wouldn’t that be changing the rules in the middle of the game? On the other hand, if CB allowed CAS for those tests but ruled CAS out for the regular SAT, wouldn’t that mean that students had to buy … 2 calculators? Further, ruling out CAS for the regular SAT would have been tantamount to admitting that the math on the calculator part of the rSAT was dumber than was the math on the old SAT.
