the iatroX advantage
traditional q-banks are just lists. iatroX is an intelligent learning system built on proven cognitive science.
1. active recall (the testing effect)
Our entire system is built on active recall—the act of retrieving information. This is scientifically demonstrated to be significantly more effective for retention than passively re-reading notes.
(source: Karpicke, J. D., & Roediger, H. L. (2008). The Critical Importance of Retrieval for Learning.)2. spaced repetition (long-term retention)
Built on the Ebbinghaus 'Forgetting Curve,' our algorithm schedules questions at the perfect, increasing intervals to interrupt the forgetting process and lock knowledge into your long-term memory.
(source: Ebbinghaus, H. (1885). Memory: A Contribution to Experimental Psychology.)your ai learning system
adaptive sequencing tells you what to study next. the dashboard shows what is weak. the Socratic Tutor helps you understand why you missed a question.
mastery learning
Our performance dashboard visually tracks your proficiency by topic, helping you apply 'Mastery Learning' to focus *only* on what you haven't mastered, ensuring you're truly ready for exam day.
(source: Bloom, B. S. (1968). Learning for Mastery.)personalised feedback loop
Your AI dashboard and Tutor create a more personalised learning loop: identify the gap, attempt retrieval, receive formative feedback, and return weak concepts into practice.
(source: Bloom, B. S. (1984). The 2 Sigma Problem: The Search for Methods of Instruction as Effective as One-to-One Tutoring.)formative assessment
Traditional Q-banks just give you a final score. Our dashboard provides real-time, diagnostic feedback to guide your *next* step, a process proven to produce substantial learning gains.
(source: Black, P., & Wiliam, D. (1998). Inside the Black Box: Raising Standards Through Classroom Assessment.)300,000+ questions answered by doctors across 40+ countries — and counting
