Answer one real exam question.
Straight from the exam bank — no account, no timer. Answer it and watch the engine calculate what it would tell you to study next.
A bag contains 4 red, 5 blue, and 3 green marbles. One marble is drawn at random. What is the probability that it is not blue?
Five steps from "not sure" to "passed."
No guesswork. No wasted study time. Just a clear path that adapts to what you actually need.
12 adaptive questions in 10 minutes reveal exactly which competencies are keeping you below passing.
Visual, interactive lessons teach what you missed. Not "memorise this formula" — actually see why it works.
Adaptive questions target your weak spots. Each one adjusts difficulty to keep you in the learning zone.
Mock exams under real conditions. Your pass probability climbs with each one until you're consistently above 240.
Walk in knowing you're ready. Your readiness score says 240+, and if you don't pass, the refund guarantee has your back.
We don't sell questions. We find your missing points.
Finds your exact gaps
After every question, the engine calculates exactly which competencies are costing you points. Not "study more algebra" — "Probability is costing you approximately 7 points. Master these four competencies first."
Teaches visually, not by memorisation
Drag the triangle. Watch the squares fill. 100+ interactive widgets that make concepts click — not just "the answer is C." You see why it works, so you remember it under exam pressure.
Tracks readiness until you're prepared
Your predicted score updates after every session. When it says 240+, you're ready. When it says 235, it tells you exactly which 5 points to close and which 3 topics will get you there. No more guessing if you've done enough.
Don't ask AI what to study. Know.
ChatGPT is genuinely excellent at teaching maths concepts. QuantegyAI isn't trying to compete with that. It's built to do something different: measure whether you're ready to pass, find exactly what's costing you points, and build the fastest path to 240.
"Great question! For the TExES Math 7-12 exam, I'd recommend reviewing the following areas:"
- Algebra and functions
- Geometry and measurement
- Probability and statistics
- Calculus concepts
- Mathematical processes and pedagogy
"Focus on your weaker areas and practice with sample questions. Good luck!"
Don't study everything.
Your largest opportunity is Probability & Statistics — it's costing you approximately 7 points.
We've built today's 18-minute lesson around the three competencies most likely to improve your readiness.
Diagnoses your mastery across every TExES 235 competency and finds the gaps costing you points.
Step-by-step explanations, interactive widgets, and adaptive practice — powered by AI, guided by the exam blueprint.
Reassesses, updates your predicted score, and prescribes the next intervention. The loop never stops until you're at 240+.

Students who passed.
Not just quotes — here's what actually happened.
100% pass rate among the students Dr. Mienie has personally tutored over the past 5 years. How this is verified ↓
METHOD-BASED RESULTS Results from students taught using the methods behind QuantegyAI. As platform users accumulate, these will be replaced with verified customer results.
"I failed twice before working with Dr. Mienie. She used the same diagnostic methods behind QuantegyAI to show me exactly what I was missing — I passed on my third attempt with a 268."
"Dr. Mienie worked with me one-on-one and I passed my certification exam!"
"Dr. Mienie's teaching methods helped me pass the 7-12 Math TExES state exam."
"Dr. Mienie and her team prepared me and I am a middle school teacher today!"
How the 100% pass rate is verified: every student Dr. Mienie has personally tutored over the past 5 years has passed their certification exam. Documented outcome records are on file and available to schools and procurement teams on request. Important: These case studies are from students Dr. Mienie taught or tutored using the methods now built into QuantegyAI — not all used the current platform. Identifying details withheld for privacy. As verified platform users accumulate, these will be progressively replaced with confirmed customer results.
