quantspell
Know your quant band
before test day.
Hard GMAT Focus quant mocks. Sit under exam conditions, get a calibrated Q-band — and a tutor in every review.
The progress view after ten sittings — Mock 0 is where it starts.
12 adaptive questions, 25 minutes, no card. Ends with an estimated Q-range.
Problem of the day
One real question, free, every day.
The tutor takes the review after you commit. In a full mock it’s 21 of these — 45 minutes, no help until review.
Stuck? Get a nudge, not the answer.
In review, the tutor starts from the trap you fell for — and points at where you slipped, not at the solution.

Questions
- Why harder than the real exam?
A test you comfortably beat tells you nothing. These sets sit at the top of the GMAT Focus quant band — closer to what the adaptive engine hands a strong scorer than an average one, so expect to score below your official Q. The value is in the questions that broke you, not the report’s headline number.
- How is the Q-band estimated?
Your raw score maps onto the 60–90 quant scale via a band table stored with each exam, always labeled an estimate. It starts from the founder’s own students’ results against their real GMAT and official mock scores, and is recalibrated as beta data lands — we would rather label an estimate honestly than quote precision we have not earned.
- What is included, and what is not?
Quant only: 21 questions, 45 minutes, one section — the shape of GMAT Focus quant. No verbal, no Data Insights, no total 205–805 score, since we do not sell the sections needed to compute one honestly.
- Refunds?
Full refund, no questions asked, until you start a sectional — once started you have seen the sealed questions, so it is not refundable. The refund policy spells out the pack rule and how to ask.
- Who builds this?
A working GMAT quant tutor — the same person behind PhysElo, a sibling physics-olympiad platform built on the same foundations. Same founder, separate everything else. Paddle is the merchant of record for purchases, so your receipt and any refund come from them.
