Raise Objection Process

Firstly, the Indian Oil Corporation Limited will release a provisional answer key, allowing candidates to raise an objection if they find any answer incorrect. Candidates should submit objections only within the prescribed deadline that will be notified by the officials. Once the objection window closes, requests submitted through other modes or after the deadline may not be considered. Candidates will also be required to provide valid proof or documents to justify their objections.

How to Calculate Marks Using IOCL Engineer & Officer Answer Key 2026?

Candidates can calculate their probable score in the IOCL CBT by matching the answers marked in their response sheet with the correct answers given in the official answer key.

1. Download the IOCL Answer Key 2026 and your response sheet.
2. Compare each answer marked by you with the corresponding correct answer.
3. Count the total number of correct answers.
4. Count the total number of incorrect answers.
5. Apply the marks allotted for each correct answer.
6. Deduct marks for incorrect answers if negative marking is prescribed.
7. Add the resulting marks to get your estimated IOCL CBT score.

IOCL Marks Calculation Formula

Estimated Score = (Number of Correct Answers × Marks for Each Correct Answer) − (Number of Incorrect Answers × Negative Marks per Wrong Answer)

Example: The official marking scheme awards 1 mark for each correct answer and deducts 0.25 marks for each wrong answer, and a candidate has 72 correct and 12 incorrect responses:
Estimated Score = (72 × 1) − (12 × 0.25) = 72 − 3 = 69 marks

IOCL Final Answer Key 2026

After the objection window closes, IOCL will examine the objections received from candidates. If any answer is found to be incorrect, the Corporation may revise the answer while preparing the final evaluation.

The final answer key is therefore different from the provisional answer key. Candidates should use the final evaluation/score released by IOCL for their final assessment rather than relying on an unofficial answer key.
