Smart Elimination Techniques To Improve CSAT Qualifying Score
In CSAT, smart guessing is as important as solving. Since there is negative marking, blind guessing is risky. But intelligent elimination works.
Here Are Practical Techniques:
1. Eliminate extreme options first (very high or very low values).
2. In comprehension, remove options that go beyond the passage context.
3. In reasoning, test options with small values instead of solving the full equation.
4. In maths, estimate the answer before calculating.
Practice sectional tests regularly. Topical tests help you identify weak areas early. Combine formula revision with timed practice for better results.
Remember, in UPSC Prelims Paper 2, accuracy matters more than attempting all questions.
