Changes in policies and regulations have continually affected UPSC exam patterns, including the structure, content, and assessment methods. Over the years, reforms have been introduced to enhance transparency, reduce subjectivity, and improve inclusiveness. These changes often reflect evolving educational standards, societal needs, and government objectives. For instance, the introduction of the CSAT in preliminary exams aimed to ensure a basic level of aptitude and comprehension skills among candidates, while the inclusion of current affairs as a significant section encourages candidates to be well-informed citizens. Such adaptations impact candidates' preparation strategies significantly.
