See it in action

See exactly where you stand — and what to fix.

Here's what QuantegyAI does for you every time you practice: a live mastery map across all six TExES domains, a readiness score that climbs with every answer, and an AI coach that knows your profile.

3,868 Calibrated practice questions
100% Pass rate — Dr. Mienie's tutored students
5 years Teaching TExES prep
15 min Average study loop

Pass rate reflects students who received 1-on-1 tutoring from Dr. Mienie and completed their exam over the past 5 years — not all platform users. Documented evidence is on file and available on request.

Inside the app

Three screens you'll live in.

Every answer you give updates all three — the mastery map, the readiness score, and what QBot coaches you on next.

You got 7/10 on probability! 🔥 Let's review conditional probability — it's your weakest area.
Can you show me \( P(A \mid B) \)?
\( P(A \mid B) = \dfrac{P(A \cap B)}{P(B)} \). Think of it as: what fraction of B events also have A happening?

Under the hood

Why you get this question next.

Most prep tools serve a fixed list. Watch one full cycle of what actually happens after a wrong answer — the numbers below are computed with the same formulas the app runs.

  1. A wrong answer, not a careless one

    The learner picks 90% on a base-rate question — the single most common wrong answer to it. The engine treats that as information, not noise.

  2. The mastery estimate drops

    Knowledge tracing revises this competency from 62% down to 21%. One wrong answer moves it that far because the model already held doubts.

  3. Ability is re-estimated

    The ability estimate \( \theta \) falls to −0.42, and every candidate question’s predicted success rate moves with it.

  4. The question bank is re-scored

    Candidates now model at 87 / 78 / 64 / 46 / 34%. The engine serves the one closest to 78% — hard enough to learn from, easy enough to keep going. Not the most informative item, which would sit near 46% and feel punishing.

  5. Mastery recovers, and the loop continues

    A correct answer lifts mastery to 57%. Reaching mastered takes 0.95 confidence plus 5 answers spanning 2 different days, so one good session cannot fake it.
