Significant changes made to the UPSC exam pattern in 2013 included the introduction of an online application process and the restructuring of the Preliminary exam into two objective papers. The first paper emphasized general studies, while the second tested aptitude skills, including reasoning and comprehension. This shift aimed to broaden the assessment of candidates beyond mere academic knowledge, emphasizing practical skills. Moreover, the new pattern introduced penalties for incorrect answers, necessitating careful consideration while answering. These changes were designed to reflect a more holistic evaluation of candidates' capabilities for civil services roles.
