HOW IT WORKS

From zero to ready in 4 steps

A process designed to maximize your learning with minimum effort.

01

Your first session

Choose your exam, set your date and start practicing. Your first sessions map your real level across every competency — no artificial test. Real exercises from minute one.

02

Optimized sessions

Each session targets the competency with the biggest impact on your preparation. 10-15 focused minutes on what truly matters.

03

Pedagogical feedback

Instant feedback with the exact rule for grammar and vocabulary exercises. 2-phase guided discovery with one re-attempt for comprehension exercises.

04

Performance prediction

Full exam simulation with real factors: stress, fatigue, and confidence dynamics. Real preparation estimate, not completion percentage.

EDUCATIONAL ENGINEERING

Educational engineering, not generic AI

Four statistical models working together to maximize your learning. This is not a chatbot — it's a system that models your knowledge with precision.

YOUR KNOWLEDGE

An EKG of your level

Each competency has its own mastery probability. 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. Related competencies benefit from each other.

85% ZONE

Always at your sweet spot of challenge

Selects exercises where your probability of answering correctly is ~85% — the zone where you learn the most. Not too easy, not impossible. Every exercise calibrated to your exact level.

Calibrated difficulty for every exercise. Level estimated and updated continuously.

EasyHard
FULL SIMULATION

Your exam, simulated thousands of times

We simulate your full exam with fatigue, 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 factors.

OPTIMAL DECISION

Every session moves your score

Evaluates each competency by its impact on your final score, time since last practice, and dependencies between competencies. Picks the one that moves your preparation the most. You don't practice randomly — every minute is optimized.

Optimizes score impact, competency unblocking, and skill balance.

PEDAGOGY

We don't give you the answer. We teach you to find it

When you fail a comprehension exercise, you don't just see red and green. You receive a guided discovery process in two phases.

Phase 1: Guided Discovery

Your answer is incorrect

What does the author say about motivation in paragraph 3?

Evidence zone: paragraph 3

You have 1 re-attempt
You got it!

+ Transferable strategy

Phase 2 →

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 phase 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.
