Building a Transparent Digital SAT Score Estimator Without Pretending It Is Exact

Score calculators look simple from the outside: enter a number of correct answers, apply a conversion table, and display a score.

The Digital SAT makes that approach unreliable.

It is adaptive, its operational scoring model is not publicly reproducible, and College Board does not publish one universal raw-to-scaled conversion table for every test form. An independent calculator therefore has two choices:

1. present false precision, or
2. make uncertainty part of the product.

I chose the second approach while building a free Digital SAT score estimator
