Preparation Strategy

To ace the number series section, we at Exam Bhai recommend a systematic approach. Do not rely on rote learning; focus on pattern recognition.

1. Memorize Squares and Cubes: Up to 40 for squares and 20 for cubes. This drastically reduces calculation time.
2. Practice Daily: Solving at least 20 series daily is mandatory. You should access our curated number series practice set for IBPS PO to refine your accuracy.
3. Pattern Recognition: Identify if the series is growing (addition/multiplication) or shrinking (subtraction/division). If the growth is explosive, suspect multiplication or squares/cubes.
4. Mock Integration: Use our platform to evaluate your performance with comprehensive banking mock tests to track your improvement over time.

Cut-Off Trends

Official cut-off data is published annually on the ibps.in portal. Historical data indicates that the IBPS PO Prelims cut-off generally hovers between 45 to 60 marks out of 100, depending on the difficulty level of the shift. Factors influencing the cut-off include the number of vacancies, the number of candidates appearing, and the sectional difficulty. Candidates should target at least 10-15 marks above the projected cut-off to ensure safety in the final merit list.

Frequently Asked Questions
