How do we check our questions?
Every question is written by TestDayPass. Before one reaches a student, it has to pass our checks, and a question that fails one stays out. Here's what we can show today, with the numbers.
Are these real SAT® questions?
No. Every question is written by TestDayPass. None is copied from an official test.
They're built for the digital SAT, across all 8 areas it tests. So far we've written 2,796: 1,639 in Math and 1,157 in Reading and Writing.
Proved by computer algebra
Math answer keys are proved by computer algebra: 1,521 of our 1,639 Math questions so far.
A question we can't prove stays out of practice until it is.
Solved twice, blind
Independent AI solvers work every question we serve without seeing the answer.
A question goes live only if both get the same answer as our key. We test the check itself too: in the run on Oct 20, 2026, we planted wrong keys on purpose, and every one was caught.
Reviewers who catch planted mistakes
Two reviewers caught every mistake we planted (36 of 36), and found no wrong answer key in the Starting Point questions.
That review was on Oct 20, 2026, of the questions that set each student's Starting Point. We planted the mistakes on purpose first, so we'd know the review catches them.
Nothing else watching
No ads and no third-party scripts on student pages.

What we don't claim yet
- How close our ranges are. We'll publish it once they've been checked against official scores from the Mar 6, 2027 SAT, released Mar 19, 2027.
- How hard each question really is. We'll measure it once enough students have answered each one.
- Results for a tutor's students. Only from official scores, from Mar 19, 2027, and only for 10 or more students.
