Introduction:
The SBI PO Exam is conducted in multiple sessions or shifts to accommodate a large number of candidates. Each session may have a slightly different set of questions, but the overall structure and weightage of the exam remain consistent. The objective section of the exam is an important component that tests the candidates' knowledge and understanding of various subjects.

Explanation:
The weightage value of the objective section does not vary significantly for different sessions or shifts of the SBI PO Exam. The exam conducting authority aims to maintain fairness and equity in the evaluation process, and therefore, the weightage of the objective section is kept consistent across all sessions.

Reasons for Consistency:
There are several reasons why the weightage value of the objective section remains the same for different sessions of the SBI PO Exam:

1. Standardization: The SBI PO Exam is a highly competitive exam, and to ensure fairness, standardization of the examination process is crucial. By keeping the weightage value of the objective section consistent, the exam conducting authority can ensure that all candidates are evaluated on an equal footing.

2. Comparison and Ranking: The objective section plays a significant role in comparing the performance of candidates and ranking them accordingly. If the weightage value of the objective section varies across sessions, it may lead to an unfair advantage or disadvantage for certain candidates. Therefore, maintaining consistency in weightage helps in a fair comparison of candidates' performance.

3. Content Validity: The objective section of the SBI PO Exam is designed to cover a wide range of topics and assess the candidates' knowledge and understanding of those subjects. By maintaining consistent weightage, the exam conducting authority ensures that the content validity of the exam remains intact. This means that the exam accurately measures the knowledge and skills required for the position of a Probationary Officer.

Conclusion:
In conclusion, the weightage value of the objective section does not vary for different sessions or shifts of the SBI PO Exam. This consistency is maintained to ensure fairness, standardization, and content validity in the evaluation process. Candidates should focus on preparing for all subjects covered in the objective section to maximize their chances of success in the exam.
