Calm, honest CAT4 familiarisation at a fair price.
Merlin Practice is made by FlightDeck Aptitude Ltd. We write original practice, explain every answer and never promise results we cannot control.
Why we built Merlin Practice.
Moving schools is stressful enough. For many families, especially those relocating to the Gulf, the CAT4 is one more unknown: an unfamiliar test, on screen, against the clock.
Merlin Practice makes it familiar. Children meet every question type with calm explanations, try the timing, and parents get a report they can read in a minute. We are honest that the CAT4 measures reasoning, and that practice is about confidence, not about changing a score.
Merlin Practice is operated by FlightDeck Aptitude Ltd, which builds timed practice software. Merlin Practice is made by FlightDeck Aptitude Ltd.

Honest about what practice can do
We report how practice is going. We never invent CAT4 scores, predict results, rank children against each other or promise a place.
