Preparation Strategy

To excel in the GK section, consistency is non-negotiable. Begin by analyzing the previous year's trend, which shows that Current Affairs, Science, and Polity form the backbone of the paper.

• Analyze Trends: Devote significant time to Science and Current Affairs, as these consistently account for nearly 40-50% of the paper.
• Practice Regularly: Utilize Exam Bhai free mock tests to simulate the exam environment, improve your speed, and test your retention of facts.
• Standard Sources: Stick to NCERTs for Geography and History, and rely on reliable monthly magazines for current events.
• Revision: Create short, topic-wise notes. For example, when studying the Indian Constitution, focus on amendments and landmark Supreme Court judgments.
• Subject Priority: If you find History overwhelming, prioritize Modern History over Ancient/Medieval, as the frequency of questions is generally higher.

Cut-Off Trends

Understanding the cut-off helps in setting realistic goals. While the cut-offs fluctuate based on vacancy count and paper difficulty, a safe target for the GK section is typically 50-60 marks.

• IMA/INA/AFA: Target 150+ total aggregate marks.
• OTA: Target 120+ total aggregate marks.
