Most exam prep marks you wrong and moves on. Testral maps 340+ past-paper questions to 89 concepts, finds your exact blind spots in under 10 questions, and tells you exactly why your mind went there — by name, with a fix.
Knowing you answered incorrectly is not feedback. Knowing that your mind confused two theorists — and always will, until you deliberately contrast them — is.
The engine shows you why it chose this question — your accuracy on the concept, the depth level being tested, and what reasoning error it's watching for. You're never in the dark about what's happening or why.
No card needed to get started. Find your gaps first.
