• The questions in the previous year NDA papers also cover the complete syllabus which leads to the overall preparation for the exam.
• Effective revision takes place by practising the NDA solved question papers.
• Time management is also a major factor while attempting the previous year question paper for the NDA exam.

## What is the NDA Exam?

NDA stands for  National Defence Academy. NDA exam is conducted for admission in the joint defence service training institute of the Indian Armed Forces, where qualified candidates of the three services i.e. the Indian Army, the Indian Navy, and the Indian Air Force are trained together before they are sent to their respective service academies for further pre-commission training.
