NDA Exam maths paper Realistic target setting

To score 135 marks out of 300, we need to solve atleast 58-60 correct questions and maximum 4-5 wrong questions so that 135 score will be achieved with accuracy. Aiming 58 correct questions with 100% accuracy is far better than aiming attempt of 80 questions with no accuracy. Negative marking can ruin your NDA exam attempt, if you fail to maintain accuracy.

No of Questions in NDA Maths paper 120
Number of questions to attempt with accuracy: Around 60 only (50% attempt)
Maximum wrong answers: 3-4
Your final score: (With 56 correct and 4 wrong) 136.67 marks

1. Accuracy will be drastically increased.
2. Chances of loosing marks in negative marking is much low.
3. Time allotted to solve 1 question is almost doubled (2.5 minutes/question)
(Its 1.25 minutes/ question if you aim to attempt all questions)
4. You can afford to leave certain unimportant chapters, and focus more on important    chapters.
(But do not dare to leave any important topic)

If at all you are aiming high attempt in Maths paper, make sure you maintain the accuracy. Because even 80 attempt is not good if you can’t maintain the accuracy (1/3rd Negative marking)
