NDA Marking Scheme For Maths

The NDA marking scheme for Mathematics is structured to evaluate candidates effectively during the examination. In the NDA exam, candidates earn 2.5 marks for each correct answer. However, to discourage random guessing, a penalty of 0.83 marks is deducted for each incorrect answer, reflecting the negative marking aspect of the NDA marking scheme 2025. The Mathematics section consists of 120 questions, totaling 300 marks, and candidates are allotted 2 hours and 30 minutes to complete this portion of the exam. Understanding this marking scheme is crucial for aspirants as it influences their strategy during the test.
