Why We Built The Gauntlet — and the Platform to Run It
The first post from tutorstack, on the day we go live.
There's a moment every tutor dreads. Your student walks back in after test day, sits down, and says the words: "That was way harder than the practice tests."
I've heard that one too many times. And the thing is, they aren't wrong. Free and official prep materials simply aren't hard enough to get a student to the top percentiles. When the real test outguns the prep, that's not just a disappointment for the student — it's a bad rap for the tutor who promised more.
From the very first student I ever worked with, I've had a single obsession: get them the highest score possible. Not a better score. The highest one possible. That obsession is what eventually forced my hand into content and software development. If the hardest material didn't exist, I'd have to build it myself.
So I did. That's where The Gauntlet came from.
What is The Gauntlet?
The Gauntlet is the most rigorous SAT prep I know how to make. It started with a book series — a Math Challenge, a Verbal Challenge, and now a Vocabulary Challenge built from the most frequently repeated SAT words — and it's grown into a full platform built on a pedagogy that's delivered an average gain of over 70 points from a baseline Reading and Writing score of 660.
Under the hood, that means the 300 hardest SAT verbal and math questions available anywhere, full-length and section-only mock tests, my high-frequency vocab and must-know math flashcards, and more than 3,000 categorized drill questions. Every single one is written and vetted by six published content experts — not generated by AI — with new content added every week.
I say the "not AI" part plainly because it matters. Hard questions are easy to fake and hard to get right. The difference shows up on test day.
The part that's new today: TutorStack
Building great content was step one. But the tutors I talked to kept hitting the same wall — they had material, but managing it across a roster of students was chaos. Spreadsheets, scattered PDFs, homework reminders that lived in their head, no real way to see who was falling behind until it was too late.
So we built the command center: a tutor dashboard that pulls everything into one place.
You can assign content from the full Gauntlet library — or your own custom drills, quizzes, and practice tests — to a single student or an entire cohort. You can track performance in real time with at-a-glance metrics: days to test, score deltas, target gaps, and each student's weakest area. And you can schedule homework with a drag-and-drop calendar that, as far as I know, nobody else in this space has. Students get automatic inbox reminders when work is due. A built-in command palette and persistent messaging mean you're not bouncing between five tabs to run your practice.
And the pricing, because somebody had to fix it
Here's the one that I think tutors will feel in their bank account: prorated billing, per student.
Most test dates don't land at the end of a month. So why would you pay for a full month of access for days a student will never use? With prorated billing you don't. It can save tutors thousands compared to other platforms. And if you'd rather have students pay for their own access, they can — connecting accounts is still simple.
Hear the whole story
This week I sat down with Mike Bergin and Amy Seeley on Tests and the Rest, THE college admissions industry podcast, to talk through where The Gauntlet came from, what's actually in the library, how the dashboard works, and why the pricing model is built the way it is. If you want the fuller version of this story — and the reasoning behind the choices — that conversation is the best place to start.
Who this is for
If you're a student chasing a top percentile, this is the hardest, most honest prep you'll find. If you're a parent trying to make sure the prep is real, look at the content and the score data. And if you're a tutor or agency, the platform was built by someone who wears the same shoes — with a transparent record of one-on-one success and an MA in Applied Linguistics — for the express purpose of making your hardest student your best result.
