The app is very useful. If this was available earlier, people would have bought it for the same cost.

Questions, answered.

What is PrepDr?

PrepDr is a postgraduate medical learning platform designed to simplify examination preparation. Previous-year examination questions are collected and transformed into structured, reference-backed answers, making learning more focused, efficient, and reliable.

Where do the answers come from?

Every answer is built using standard textbooks, specialty-specific references, and current clinical guidelines where appropriate. Before publication, answers undergo a structured review process to ensure they are accurate, exam-oriented, and easy to revise.

Why should I choose PrepDr over simply reading standard textbooks?

Standard textbooks are designed to teach concepts comprehensively. PrepDr is designed to help you convert that knowledge into exam performance. By transforming previous-year questions into concise, structured, mark-oriented answers, PrepDr helps you revise efficiently while staying grounded in trusted references across every subject.

Are the questions and answers updated regularly?

Yes. We continuously review and update both the question bank and answers to reflect recent examination trends, current clinical guidelines, and important developments, ensuring the content remains relevant and up to date.
