I’d rather see kids taking tests of slightly different difficulty than the widespread shameless cheating which is going on with the current system. That’s completely unfair to the kids who aren’t sleazy cheaters and it calls the entire system into questions. Also, much as the college board would like us to believe these SAT scores are handed down from God, actually, we see lots of kids taking and retaking and the scores bounce up and down quite a lot. And at the higher levels the wonderful equating process just ends up meaning if you got a few wrong on one day you are getting a lower score than if you got the same number wrong on another day. The fact that kids with scores hundreds of points lower than you may have found the problems more or less difficult often isn’t relevant to the high performing students. The issues with mixing up problems from old tests are really quite minor in the context of these greater problems.
