Books for SSB Interview Preparations

For NDA exam preparations, the student should solve previous years question papers/model question papers daily. The previous question papers and mock tests will help you to get familiar with the syllabus, weightage of question and exam pattern. It will also give you information about the difficulty level of the question paper and which type of question can save them more time. With the help of NCERT and Previous years question papers, you can ace NDA exam easily. All the previous years' question papers are in PDF format. Download now

Strategies to prepare for NDA exams:

As this exam consists of 2 phases, so we need to prepare accordingly for that exam.

Relax your mind

To start preparation, the candidate must first free their mind from all the distractions and stresses related to studies. After that, candidates can plan their studies. To relax their mind, the candidates should try meditation, and it will be helpful for them to start their preparation to begin anew.

Avoid distractions

For the time being, try to avoid TV, Mobiles and Games. At least when you are studying. It will help you to learn without being distracted.

Check out the syllabus:

Before planning a study, you need to check the syllabus first and then try to start with the most weighted topic/subject. Try not to cover everything in one day. Give yourself time to understand things and then study accordingly.

Plan your study:

Planning will help you organize and manage time. This will make your study easier. Being organized will help you to study the way you plan, and only then you will be able to complete the course on time.

Focus on your strengths:

It is the most important part of your preparation. Previous years question papers and mock tests can help you focus on your strengths. By regularly practising those papers, you will be able to know your strengths where you can score high and on which part you still need to work hard.

Revision is must:

When you realize that all your syllabus is about to end, then the candidates have to take the previous studies topics and try to revise daily, so that they do not forget what they have during the early days of their preparation.

The result Of NDA 2 will be announced on September 14 by the Union Public Service Commission (UPSC). The UPSC will prepare a list of candidates who scored minimum qualifying marks in the exam shall appear to SSB and Physical test.

The NDA Final result will be declared after the written test and SSB Interview. Candidates can check the NDA result on the UPSC website, which will be displayed in pdf format. Candidate can search their roll numbers and see their result. If they found their roll numbers in the list have qualified the exam.

All the candidates who have successfully passed the written examination will have to register themselves with the Directorate General for recruitment on the website www.joinindianarmy.nic.in. Through this website above, candidates will be allotted selection centres.
