Adaptive routing
Adaptive routing is the digital SAT's rule that your performance on the first module of a section decides whether the second module you receive is the harder or the easier form.
Also written as: module-adaptive delivery, multistage testing
Why it matters
It is the single most consequential fact about digital SAT scoring, and it inverts how preparation should be spent. The easier second module carries a lower score ceiling, so a student routed into it cannot reach the top of the scale that day no matter how well they answer it. That makes accuracy on medium questions in Module 1 worth more than skill at the hardest questions — the opposite of the paper-SAT instinct.
What people get wrong
That an easy second module is good news. It is usually the tell that Module 1 went badly. It is also worth knowing that the two sections route independently: Reading and Writing can send you one way and Math the other in the same sitting.
