A significant change in the UPSC examination pattern in recent years has been the introduction of negative marking in the Prelims examination. This change aims to discourage random guessing and promote informed and educated answers. Under this system, candidates lose 0.33 marks for every incorrect answer, which compels aspirants to focus on accuracy rather than attempting to answer every question haphazardly. This shift also emphasizes the need for thorough preparation and understanding of the syllabus, ensuring that candidates adopt a more strategic approach in their exam attempts.
