NDA is one of the most attempted exam.

Focus on General Knowledge and English Subject as Proficiency in English is required for clearing the NDA examination. Your English is not only tested in written test but if there is fluency in your English, then it may leave the good impression on selectors also at the time of interview. As General Knowledge is the part of syllabus so prepare it well. You can strong your GK portion by reading newspapers, magazines, journals, refer books of prominent writers that focus on current affairs, etc.

It is very important to do the preparation in right direction. By solving previous year questions, your speed will be enhanced as well as you will get the idea about the NDA exam pattern of the examination and difficulty level of the questions asked in the examination.

Selection through NDA is based not only on the written test but your personality and health also plays a major role in it. So don't panic. Take out time for studies and health equally.

Good Luck.
