1️⃣ Relying Too Much on One Source for Static Subjects
📌 Mistake: Many aspirants believe that a single book (like NCERTs or Laxmikanth) is enough to cover an entire subject.
📌 Why It’s Dangerous: UPSC asks analytical and conceptual questions that require a multi-source approach. Sticking to one book without cross-referencing limits understanding.
📌 Solution:
✔ Follow a structured study plan – NCERTs for basics + standard books for in-depth understanding.
✔ Complement books with government reports, PIB updates, and Yojana/Kurukshetra magazine.
✔ Cross-check facts from different sources to get clarity on conflicting information.

2️⃣ Not Focusing on Previous Year Question Papers (PYQs)
📌 Mistake: Many aspirants ignore UPSC previous year questions (PYQs) and rely only on reading books.
📌 Why It’s Dangerous: UPSC has a pattern of repeating themes, and understanding how questions are framed is key to tackling Prelims effectively.
📌 Solution:
✔ Analyze at least the last 10 years’ PYQs to understand topic weightage.
✔ Identify question patterns – factual, conceptual, statement-based, elimination techniques.
✔ Use PYQs as a revision tool – Convert questions into flashcards for quick recall.

3️⃣ Ignoring the Importance of Elimination Techniques
📌 Mistake: Many aspirants either blindly guess or skip difficult questions, not using logical elimination techniques.
📌 Why It’s Dangerous: In Prelims, eliminating wrong options is as important as knowing the right answer. A strategic approach improves accuracy and minimizes negative marking.
📌 Solution:
✔ Learn elimination techniques – Look for extreme words (always, never, only) which are usually incorrect.
✔ Use logic, not assumptions – UPSC questions have hints in statements that can help eliminate wrong choices.
✔ Practice with mock tests to build confidence in elimination strategies.

4️⃣ Overlooking Current Affairs or Studying Them Superficially
📌 Mistake: Some aspirants focus only on static subjects, while others read current affairs without linking them to static concepts.
📌 Why It’s Dangerous: UPSC asks conceptual questions from current affairs, not direct facts. Without linking them to Economy, Polity, Geography, and Science, current affairs become useless.
📌 Solution:
✔ Follow a structured approach – Read daily news but focus on analysis.
✔ Use PIB, Yojana, and government sources rather than relying on random YouTube summaries.
✔ Connect news with static topics – Example: If RBI announces a new policy, revise Monetary Policy concepts from Economy.

5️⃣ Underestimating CSAT Paper 2
📌 Mistake: Many aspirants assume CSAT is easy and fail to practice.
📌 Why It’s Dangerous: The difficulty of CSAT has increased significantly in recent years. Many aspirants fail Prelims despite scoring well in GS Paper 1.
📌 Solution:
✔ Treat CSAT as a serious paper – Aim for at least 80+ marks for safety.
✔ Practice previous year CSAT papers to understand question trends.
✔ Solve maths, reasoning, and comprehension questions regularly to build speed and accuracy.

6️⃣ Not Taking Mock Tests Seriously
📌 Mistake: Many aspirants either avoid mock tests or take them without analyzing mistakes.
📌 Why It’s Dangerous: Mock tests help build exam temperament. Without them, aspirants panic during Prelims.
📌 Solution:
✔ Take full-length Prelims mocks in exam-like conditions.
✔ Analyze mistakes – Identify weak areas and improve them before the actual exam.
✔ Develop time management skills – Aim to attempt 85+ questions with accuracy.
