Analytical Ability and Data Interpretation
- BODMAS Priority Trap — Many fail Order: Brackets, Of (exponents), Division/Multiplication (left-to-right equally), Addition/Subtraction (left-to-right equally). Remember DM and AS are equal priority pairs, not hierarchies.
- Divisibility by 11 Quick Check — Alternate sum: Add odd-position digits, subtract even-position digits. If result is 0 or divisible by 11, original number is divisible by 11 (e.g., 121: 1+1−2=0).
- Clock Angle Formula — Angle between hands = |30H − 5.5M| degrees, where H=hour, M=minutes. If result >180°, subtract from 360° for smaller angle. Saves calculation time.
- Percentage-to-Fraction Speed Conversions — Memorize: 12.5%=1/8, 16.67%=1/6, 33.33%=1/3, 62.5%=5/8, 87.5%=7/8. Instantly simplify Data Interpretation calculations without decimals.

- KCR's Fast Timeline — November 2009 Indefinite fast, December 9, 2009 Centre announces separate Telangana process. 9 days that accelerated statehood movement decisively.
Banking and Financial System
- CRR vs SLR Quick Difference — CRR (Cash Reserve Ratio) held with RBI in cash, earns no interest. SLR (Statutory Liquidity Ratio) held as liquid assets (bonds/gold), earns interest.
