The 20-Minute Prelims Time Management Protocol

In SBI PO Prelims, you have exactly 20 minutes to attempt 35 Quantitative Aptitude questions. Attempting to solve all 35 is a recipe for disaster. The topper strategy targets 24-28 high-accuracy attempts.

Allocate your 20 minutes in two distinct rounds: Round 1 (first 8 minutes) for rapid score boosters, and Round 2 (next 12 minutes) for selected DI sets.

Key Strategy Takeaway

Never touch a complex caselet DI in the first 5 minutes of SBI PO Prelims.

Speed Boosters: 15 Marks in 7 Minutes

Every SBI PO Prelims paper contains 12-15 questions from these three categories:

  • Simplification & Approximation (5 Q): Master decimal rounding, fraction-percentage tables, and digital sum.
  • Quadratic Equations (5 Q): Master sign methods to determine roots in 20 seconds without factoring out full polynomials.
  • Missing or Wrong Number Series (5 Q): Recognize difference-of-differences, alternating prime shifts, and n² ± k patterns.

Mastering Mains Data Analysis & Interpretation

SBI PO Mains does not feature standalone arithmetic questions; it embeds arithmetic into Data Interpretation (e.g., a Time & Work pipeline represented via Radar Charts or a Probability Caselet). Practice converting raw paragraph data into structured tables before reading question stems.
