Calculating sectional cutoff scores for the IBPS PO Exam is an important step to determine the eligibility of candidates for further rounds of the selection process. Here are the specific instructions to calculate sectional cutoff scores using the answer key:

1. Understand the Exam Pattern:
- The IBPS PO Exam consists of multiple sections, such as Quantitative Aptitude, Reasoning Ability, English Language, General Awareness, and Computer Knowledge.
- Each section carries a specific weightage and has a fixed number of questions.

2. Obtain the Answer Key:
- The answer key for the IBPS PO Exam can be obtained from the official website of IBPS or other reliable sources.
- The answer key provides the correct answers for all the questions asked in the exam.

3. Analyze the Answer Key:
- Compare your answers with the answer key and identify the number of correct and incorrect answers for each section.
- Calculate the raw score by giving one mark for each correct answer and deducting a fraction of marks for incorrect answers (if negative marking is applicable).

4. Determine the Total Marks:
- Add up the raw scores obtained in each section to determine the total marks secured by the candidate.

5. Check the Cutoff Scores:
- The cutoff scores for each section are predetermined by the conducting authority, i.e., IBPS.
- These cutoff scores may vary each year based on factors such as the difficulty level of the exam and the number of vacancies.
- The cutoff scores are usually announced along with the result of the exam.

6. Compare Scores and Cutoffs:
- Compare the total marks obtained by the candidate with the cutoff scores for each section.
- If the candidate's score is equal to or above the cutoff score for a particular section, they are considered qualified in that section.

7. Analyze Overall Performance:
- After calculating the sectional cutoff scores, it is important to analyze the overall performance.
- If the candidate has cleared the cutoff scores for all sections, they are eligible for further rounds of the selection process.
- If the candidate has not cleared the cutoff scores in any section, they may not be eligible for further rounds.

In conclusion, calculating sectional cutoff scores for the IBPS PO Exam involves analyzing the answer key, determining raw scores, comparing with cutoff scores, and analyzing overall performance. It is crucial to check the official website of IBPS for the most accurate and up-to-date cutoff scores.
