Government & Defence Entrance Exam

The Indian Coast Guard arranges the marks of the candidates in the case if the candidates attempted the CGCAT examination in different shifts to attain a rational approach to the marks. Nevertheless, the normalization process is made using a statistical method before the results could be out. 

The formula for calculating the normalized marks is:

Mij: The normalized marks of the jth candidate for ith shift 

Mtg: Average mark of the top one percentiles of candidates of each shift 

Mqgm: The total of mean marks in the shift with the highest mean and standard deviation of marks among all the shifts 

Mti: It means the mean of marks of the 0.1% the highest scorer in the ith shift 

Miq: Mean marks + Standard Deviation where I represents a shift. 

The CGCAT is an examination with 100 multiple choices questions in a two hours span. To contains the various topics in the syllabus there are Five sections includes General Awareness, English, Numerical Ability, Reasoning, and Military Aptitude. 

Few important points related to NDA vacancies are given below:

• NDA vacancies are provisional and may change depending on the availability of training capacity of the National Defence Academy and Indian Naval Academy
• Candidates are required to specify clearly in the online NDA application form, the services for which they wish to be considered in the order of their preferences
• Candidates are also advised to indicate as many preferences as they wish for NDA recruitment so that while offering appointments due consideration can be given to the preferences as per their ranks in the merit list
• Candidates should note that they will be considered under NDA recruitment 2022 for appointment to those services only for which they have expressed their preferences
• UPSC will not entertain any request for addition/alteration in the preferences indicated in the NDA Recruitment application
• Admission will be offered to candidates on the basis of NDA results of the written exam and SSB Interview 

To determine your eligibility for NDA 1 and NDA 2 in 2025, we need to consider the age requirements set by the Union Public Services Commission (UPSC).

For NDA 2025, the age requirement is that candidates must have been born between January 2, 2006, and January 1, 2009.¹ Given your date of birth is April 18, 2006, you meet this criterion.

However, the specific eligibility for NDA 1 and NDA 2 in 2025 depends on the exact notification released by the UPSC, which typically includes detailed eligibility criteria, including age limits.

In general, though, with your date of birth, you should be eligible to apply for both NDA 1 and NDA 2 in 2025, provided you also meet the other eligibility criteria, such as educational qualifications and physical standards. Always check the official UPSC website for the most accurate and up-to-date information regarding NDA eligibility and application processes.
