How it works
How you get from studying to passing
No shortcuts — just focused repetition until it sticks. Practise by module, learn from the explanation on every question, track your weak spots on the dashboard, and repeat until you clear the 75% pass mark with room to spare.
Practice by module
Work through question banks for every Part 66 module, plus real past exam papers, so you know exactly what to expect on the day.
Learn from every answer
Every question comes with an explanation, not just a correct answer — wrong guesses turn into things you actually understand.
See where you stand
Your dashboard tracks your best score per module and flags the weak spots, so you always know what to study next.
Repeat until it's automatic
Retake modules, watch your score climb past the 75% pass mark, and check the rankings to see how you compare. You practice, you improve, you pass.
Sit the real exam before the real exam
The new exam simulator recreates the exact EASA Part 66 format for your licence category — the official question count, a live countdown and the 75% pass mark — so nothing on exam day is a surprise.
- Official EASA question count
- Live countdown timer
- 75% pass mark & scoring
- Full explanations at the end
