How to Calculate Score Using the Key

Estimating the probable score requires careful application of the marking scheme. Therefore, count correct, incorrect and unattempted questions section-wise. Additionally, the marking varies for single-correct and multi-correct questions. Subsequently, the merit list considers the best three section scores.

• Marking Scheme: +3 for each correct single-answer MCQ, -1 for incorrect, 0 for unattempted.
• Total Marks per Section: 60 (20 MCQs)
• Total Marks: 240 across all four sections
• Merit Calculation: Best three section scores out of four (maximum 180)
• Formula: (3 x Correct) – (1 x Incorrect) = Section Score

Objection Process

The objection window allows candidates to challenge any incorrect or ambiguous answer. Furthermore, supporting evidence such as textbook references must be provided. Subsequently, the subject experts examine each objection before issuing the final key.

• Log in to nestexam.in with application number and password.

• Select the question number and the contested option.
• Upload supporting documents or reference material.
• Pay the prescribed objection fee for each challenge.
