This article makes it sound like the new SAT is not an improvement.
“Still, the test seems to have more questions that are vague, arbitrary or ambiguous. For example, one question that asks why certain facts are mentioned has one answer choice that says “offer an explanation” and another that says “support a conclusion.” But in this case, the conclusion and the explanation were basically the same thing, so what should you pick? The College Board wants you to pick the explanation choice, but there’s really nothing wrong with the conclusion choice.”
^^^^this!
My son found that they new (March) SAT reading questions were ambiguous and arbitrary- much more so than the ACT.
