The SAT, by design, covers the entire difficulty range. Parts are easy, parts are hard, such that about half of students get less than half of it right, and 0.1% of students ace it. It's not merely pass-fail, they're trying to give a pretty granular rank to each student.

Thus, if the test is worth taking for a student (because they want to go to college), it's probably worth cheating on. Students outside the top 0.1% can appear better than their peers to improve their odds of getting into better universities, and students in the top 0.1% tend to be there due to intense extrinsic pressure, which may drive them to cheat to increase their certainty of acing it.

For a competent student, it's not hard to get an acceptable grade. For every student, it's difficult to achieve an exceptional grade.
