- CSAT Paper II: 80 questions each worth 2.5 marks. A wrong answer deducts 0.83 marks. Caution is your best friend here.
Note: CSAT is a qualifying paper. You need 33% to pass but clearing it comfortably ensures no last-minute surprises.
Factors Affecting Difficulty & Cut-Off of Prelims
- Question Paper Pattern
- Evolution of question paper pattern plays a significant role in determining difficulty level. For instance shift from straightforward factual questions to more analytical & conceptual questions requires aspirants to have a deeper understanding of concepts rather than just rote learning.
- Increased emphasis on multi-statement questions that demand candidates to apply logic & critical thinking skills to eliminate incorrect options making even known topics appear challenging.
- Balanced mix of static & dynamic questions with some years seeing a surge in current affairs making it harder for aspirants to predict & prepare adequately.
- Current Affairs Intensity
- Intensity & breadth of current affairs questions can significantly raise difficulty level. Some years questions are deeply rooted in niche areas of international relations, government schemes & socio-economic developments.
- Dynamic nature of current affairs especially questions that link contemporary events with static portions tests both the recall ability & analytical thinking of candidates.
- Unpredictable Topics
- Inclusion of less commonly covered topics such as Art & Culture, Environment-related international conventions & unexpected areas like sports policies or obscure government initiatives can catch even well-prepared candidates off guard.
- Trend of integrating interdisciplinary topics for example linking technology with environment or polity with international organizations increases complexity.
- Difficulty Level of CSAT
- CSAT paper’s toughness indirectly impacts GS cut-off. A particularly challenging CSAT paper might result in fewer candidates qualifying thus slightly lowering GS cut-off due to the limited pool of candidates.
- Increasing complexity of comprehension passages & logical reasoning problems in CSAT papers demands strong analytical skills often underestimated by aspirants.
- Number of Vacancies
- Number of vacancies announced each year directly influences the cut off. Fewer vacancies lead to higher competition thus pushing cut-off marks upwards.
- Conversely years with a higher number of vacancies might see a slightly relaxed cut-off although competition remains intense.
- Overall Candidate Performance
- Overall performance of candidates can affect cut-off. If a significant number of candidates perform exceptionally well cut-off will naturally rise.
- This is influenced by accessibility of quality coaching, widespread use of online resources as well as standardization of preparation materials.
- Negative Marking Impact
- Presence of negative marking adds a psychological layer to exam strategy. Candidates who attempt questions aggressively without calculated risk taking may end up with lower scores due to incorrect answers.
- Conversely a conservative approach might lead to fewer attempts risking falling below cutoff despite high accuracy.
- Exam Day Pressure
- Psychological factors such as exam anxiety, time management issues as well as ability to maintain focus under stress play a crucial role in determining performance.
- Factors like unfamiliar exam centers, last minute changes in exam patterns or personal stress can disproportionately affect outcomes.
- Standard of Mock Tests
- Quality of mock tests taken during preparation impacts real exam performance. Mocks that are either too simplistic or unrealistically tough can skew confidence & preparedness.
- Regular analysis of mock tests helps in identifying patterns, strengths & weaknesses which is critical for optimizing exam-day strategies.

How Many Questions to Attempt in GS Paper I?
- Ideal Attempt Range: 75-90 Questions
Why this range?
- Cut-off Trends: Vary yearly. In 2023 General category cut-off was 75.41 while in 2020 it was 92.51. This fluctuation highlights importance of both accuracy & a sufficient number of attempts. Aiming for 70-85 questions provides a cushion against tough papers & varying difficulty levels.
- Accuracy Over Guesswork: Attempting 70-85 questions balances risk & reward. Too few attempts may fall short of the cutoff while too many guesses can increase negative marking. This range allows for a strategic blend of sure-shot answers & calculated risks.
- Strategic Elimination: Focus on eliminating incorrect options to make educated guesses. This method improves your chances even when you’re unsure about correct answer.
- Mock Test Analysis: Consistently scoring above 100 marks in mock tests ensures better real exam performance. Regular mock tests also help identify your optimal attempt range.
Approach
- Focus on maximizing accuracy while maintaining an optimal attempt range. Attempting too many questions increases risk of negative marking while too few may not secure a safe score.
- Use intelligent guessing techniques based on elimination methods. When you can confidently eliminate two options making an educated guess becomes statistically favorable.
- Balance speed & accuracy by dividing the paper into rounds: first attempting sure-shot questions then revisiting tougher ones with an elimination strategy.
Example:
- Attempt 80 questions.
- 10 wrong answers = −6.6 marks (10 x 0.66).
- You need at least 53 correct answers to safely clear a 100-mark cut-off.

- Develop a strong foundation in NCERTs & standard reference books. Understanding core concepts helps tackle even twisted questions.

Don’ts:
- Avoid Blind Guessing.
- Don’t Over rely on One Source.
- Refrain from Spending Excessive Time on a Single Question.
- Neglecting CSAT.
