13.16 Marks scored by the candidates in Computer Based Examination, if conducted in multiple shifts, will be normalized by using the procedure published by the Commission vide Notice dated 02.06.2025. Normalized marks of Paper-I (Qualifying in Nature) will be used to shortlist the candidates to appear in Paper-II. Only normalized scores of Paper-II will be used to determine final merit.

13.17 The Final Answer Keys will be used for processing the result of the Computer-Based Examination. Final Answer Keys as well as marks will be made available on the website of the Commission after the declaration of the result of the Computer-Based Examination.

13.18 In this Examination, a few posts are common for Mechanical and Electrical Engineering. Since the engineering branches are different, different question papers are served to the candidates of Mechanical and Electrical Engineering. Because of altogether different disciplines/question papers, difficulty levels between the two question papers may vary. Accordingly, scores of Mechanical and Electrical Engineering in the paper of this Examination shall also be normalized with each other for determining the final merit and cut-off marks. In addition, marks of Paper in Part-D/Part-E/Part-F for the post in IMD shall also be normalized by treating them as different shifts.

13.19 The schedule of the Examination indicated in the Notice is tentative. Any change in the schedule of the Examination will be informed to candidates only through the website of the Commission

13.20 There shall be no provision for re-evaluation/ re-checking of scores of any stage/ paper(s) of the Examination. No correspondence in this regard shall be entertained.
