Let’s dispel a few myths. Myth number one: Colleges that accept the SAT or ACT prefer one over the other. This one is easy--there is no favorite. Really. They don’t care. Students can take either a practice or a real version of both tests and find out which they like better or which yields higher scores (you can Google “SAT to ACT conversion scale” to find out how the scores compare to each other).
Myth number two: The ACT is easier. This is a little less clear-cut. What constitutes a “good score” for the SAT or ACT is determined on a curve based on how well you do in comparison to your peers. While it’s certainly true that some students will do better on either the SAT or ACT, the discrepancy is rarely very large; it is extremely unlikely that a student will score in the 99th percentile on one but only the 50th percentile on the other.
