The preliminary exam is generally considered less difficult compared to the main exam, primarily due to its focus on basic general knowledge and current affairs. The preliminary exam often comprises multiple-choice questions, testing candidates' awareness and comprehension of various subjects. In contrast, the main exam requires in-depth understanding, critical analysis, and coherent essay writing on complex topics. Candidates must not only recall facts but also demonstrate their ability to connect ideas and formulate balanced arguments in the mains. Thus, while both phases are challenging, the main exam demands more rigorous preparation and a deeper level of understanding.
