From zero to ready in 4 steps
A process designed to maximize your learning with minimum effort.
Diagnostic test
15 items that establish your profile across key competencies. The engine starts with a real estimate of your level — not an empty bar.
Optimized sessions
The engine evaluates each competency by its impact on your score and picks the one that moves your pass probability the most. 10-15 focused minutes on what matters.
Pedagogical feedback
Discrete competencies: instant feedback with the exact grammar rule. Strategic competencies: 2-phase guided discovery with one re-attempt.
Performance prediction
10,000 simulations of your full exam. With stress, fatigue, and confidence dynamics. Real preparation estimate, not completion percentage.

EDUCATIONAL ENGINEERING
Educational engineering, not generic AI
Four research-grade statistical models working together to maximize your learning. This is not a chatbot — it's an educational engineering system that models your knowledge with precision.
An EKG of your knowledge
Each of your 222 competencies has its own mastery probability. Each answer updates ONLY that competency with statistical precision. If you get something hard right, it counts more. If you get something easy wrong, that also weighs more. Your profile reflects exactly what you know — not what you've completed.
Difficulty-weighted updates. Forgetting curve with dynamic stability. Related competencies benefit from each other.
Always at your sweet spot of challenge
The engine calculates your latent ability and selects exercises where your probability of answering correctly is ~85% — the optimal learning zone. Not too easy (boredom), not impossible (frustration). Every exercise is calibrated to your exact level.
Calibrated difficulty for every exercise. Ability level estimated and updated continuously.
Your exam, simulated 10,000 times
We simulate your full exam ten thousand times. With accumulated fatigue, exam stress, and confidence dynamics. When we give you a readiness estimate, it's a real statistical calculation — not a percentage of exercises completed.
Each simulation replicates the full structure of your exam with realistic stress and confidence dynamics.
Every session moves your score
The engine evaluates each competency by its impact on your final score, uncertainty, blocking dependencies, time since last practice, and cognitive cost. It picks the one that moves your pass probability the most. You don't practice randomly — every minute is optimized.
Optimizes score impact, information gain, competency unblocking, and time since last practice.
PEDAGOGY
We don't give you the answer. We teach you to find it
When you fail a strategic exercise, you don't just see red and green. You receive a pedagogical guided discovery process in two phases.
Phase 1: Guided Discovery
What does the author say about motivation in paragraph 3?
Evidence zone: paragraph 3
+ Transferable strategy
Phase 2: Reveal
Look at lines 15-18: 'although initially reluctant, she eventually...' The key is 'eventually'
Precise evidence: lines 15-18
Transferable strategy
Look for contrast words (although, however, yet) that signal position changes
Your progress is honest
Your knowledge model updates with your first answer — before feedback. We don't inflate your progress with assisted answers.
Transferable strategies
Every scaffold ends with a strategy you can apply to other texts. You don't memorize answers — you learn to solve.
Listening too
In audio exercises, Phase 1 tells you what to listen for and replays the exact segment. Phase 2 shows you the transcript with key signals highlighted.
Everything you need to pass
Real-format exercises, smart correction, and mock exams when you're ready.
Real exam format
Exercises identical to the official format: all 7 Reading parts, 4 Listening, 2 Writing. No surprises on exam day.
Writing with Cambridge corrector
4 Cambridge criteria (content, communicative achievement, organization, language). Score 0-5 per criterion with cross-skill observations that improve your grammar.
Smart mock exams
The engine decides when you're ready. Requires enough sessions, competency variety, and recovery time. No premature mock exams.
Progress across 222 competencies
Visualize your mastery of each competency. Forgetting curve, trends, performance prediction. Fully transparent.
