The 3-Round Exam Hall Strategy
Round 1: Absolute Certainty (First 45 Minutes)
Solve only questions where you are 100% confident in the answer.
Bubble these answers immediately onto the OMR sheet to prevent end-moment bubbling panics.
Target: 35 to 45 Questions (~70–90 Marks locked in).Round 2: 50-50 Elimination (Next 40 Minutes)
Attempt questions where you have eliminated 2 incorrect options.
When you are down to 2 choices, probability dictates a 50% success rate. Even with negative marking, attempting 20 such questions yields:
- 10 Correct (+20 Marks)
- 10 Incorrect (-6.66 Marks)
-
Net Gain: +13.34 Marks
Target: 25 to 35 Questions.Round 3: High-Risk Analytical Logic (Last 25 Minutes)
Evaluate remaining questions using pattern recognition, extreme word elimination ("Always", "Never", "Entirely"), and contextual clues.
Never attempt questions where all 4 options are completely unknown to you.---
