Weightage of Marks in NDA Exam

The National Defence Academy (NDA) exam is conducted by the Union Public Service Commission (UPSC) for the selection of candidates for the Indian Army, Navy, and Air Force. The exam consists of two papers - Mathematics and General Ability Test (GAT).

Mathematics Paper:
The Mathematics paper in the NDA exam is designed to test the mathematical abilities of the candidates. It consists of various topics such as Algebra, Trigonometry, Geometry, Calculus, Statistics, and Probability. The weightage of marks for the Mathematics paper is as follows:

- Total Marks: The Mathematics paper carries a total of 300 marks.
- Number of Questions: The paper consists of 120 questions.
- Marking Scheme: Each question carries 2.5 marks.
- Negative Marking: There is negative marking in the Mathematics paper, with 0.83 marks deducted for each incorrect answer.

Therefore, the weightage of marks for the Mathematics paper can be calculated as follows:
Weightage = (Total Marks/Number of Questions) x Marks per Question

General Ability Test (GAT) Paper:
The General Ability Test (GAT) paper in the NDA exam is divided into two sections - English and General Knowledge. The GAT paper aims to assess the candidate's general awareness, English language skills, and reasoning ability. The weightage of marks for the GAT paper is as follows:

- Total Marks: The GAT paper carries a total of 600 marks.
- English Section: The English section carries 200 marks.
- General Knowledge Section: The General Knowledge section carries 400 marks.
- Marking Scheme: Each question carries 4 marks in the GAT paper.
- Negative Marking: There is negative marking in the GAT paper, with 1.33 marks deducted for each incorrect answer.

Therefore, the weightage of marks for the GAT paper can be calculated as follows:
Weightage = (Total Marks/Number of Questions) x Marks per Question

Overall Weightage:
To calculate the overall weightage of the NDA exam, we need to consider the total marks of both papers. The Mathematics paper carries 300 marks, while the GAT paper carries 600 marks. Therefore, the overall weightage of marks for the NDA exam can be calculated as follows:

Overall Weightage = (Mathematics Weightage + GAT Weightage) / (Mathematics Marks + GAT Marks) x 100

It is important to note that the weightage of marks may vary slightly from year to year, depending on the difficulty level of the exam. It is advisable for candidates to refer to the official notification and exam pattern released by the UPSC for the most accurate and up-to-date information regarding the weightage of marks in the NDA exam.
