The consequences of negative marking in UPSC prelims can be significant, as incorrect answers lead to a reduction in total marks. This system encourages candidates to prioritize accuracy over guessing, fostering a more strategic approach to answering questions. To minimize risk, aspirants should focus on attempting questions they are confident about, rather than rushing to answer all items. An understanding of the exam pattern and effective time management during the test can also assist in making more informed choices. Thus, awareness of negative marking influences preparation and answering strategies during the UPSC prelims.
