The Union Public Service Commission organises NDA and NA Exam for admission to the Army, Navy and Air Force Wings of the National Defence Academy and Indian Naval Academy Course. The UPSC conducts NDA and NA Exam two times in a year in offline mode as described below.
NDA and NA Examination (I)
NDA and NA Examination (II)
The selection and examination process remains the same for NDA and NA I & II. The candidates will face two stages to get admission in National Defence Academy and Naval Academy. The candidates have to pass stage I to face stageII.
Written Examination
SSB Interview
The UPSC conducts the NDA Written Exam in offline mode. The UPSC is responsible to set the exam pattern and syllabus for this exam. The UPSC is a renowned organisation for conducting examinations to recruit officers. So it always maintains the standard of exams. The organisation does not ask extremely hard questions and topics in the exams but it asks the comprehensive questions to check the understanding level of topics. So the candidates are advised to prepare the topics in brief. They should practice NDA Mock Tests and previous year papers to strengthen their preparation.
The candidates are also advised to check the NDA Exam Eligibility to avoid circumstances in the selection process. The UPSC releases the admit cards on its official website before 10 days (minimum) to attend the examination. The UPSC reserves the right to change exam schedule, pattern, syllabus, and examination rules. The organisation regulates the NDA Exam in a disciplined manner.
The NDA and NA Exam will be held on 6 September 2020 (Important Dates). There will be two papers in two sittings of a day that are explained below. The duration of each sitting will be 2 hours and 30 minutes.
Mathematics (120 MCQs )
General Ability (150 MCQs)
A separate booklet with an OMR seat will be issued for each paper containing bilingual MCQs (Hindi and English Language). Paper I contains 120 MCQs from only Mathematics and PaperII contains 150 MCQs from English Language and General Knowledge. There will be 50 MCQs from English Language and 100 MCQs from General Awareness in PaperII. Each question contains four options as an ordinary exam but MCQs required comprehensive knowledge of the topics. See in the below table to understand the accurate exam pattern of NDA and NA.

The UPSC sets 1800 Marks for NDA and NA Marking procedure equally divided in Written Exam and SSB Interview. Both the written exam and SSB Interview contains 900 Marks separately. The written exam contains Mathematics and General Ability papers of 300 Marks and 600 Marks respectively. The General Ability Paper contains English Language and General Awareness of 200 Marks and 400 Marks in the written exam. Each MCQ of Mathematics contains 2.5 Marks and General Awareness contains 4 Marks.
The negative marking is a mark deducting factor in the NDA and NA Exam Marking Scheme. There will be 1/3 of each MCQ Marks deducted in both Mathematics and General Ability Paper. This is an offline exam and marking two or more options simultaneously in an answer is the part of negative marking. There will be no penalty for unattempted MCQ in the NDA Exam. The candidates are advised to be aware at the time of darkening the oval because the answer can not be changed if it once darkened.
The three wrong answers penalty is equal to the one right answer marks that can lessen huge scores of the candidates if they answered questions inaccurately. So it is advisable to mark the answers with accuracy.

NDA Preparation Tips
· You need a proper study plan to finish NDA exam within prescribed time limit. Go through the topics in syllabus and start with the ones that you are good at. Practise mathematics problems by memorising formulas to become faster. Same with Physics and Chemistry, learn chemical equations by writing over and over.
· Make mathematics your strong suit, practise questions to solve them within time to increase efficiency. The trick here is to mug up math formulas by heart, so they come in handy while solving a problem.
· Become smart by attempting questions that you are sure of first, then come to the questions you’re in doubt. But don’t attempt them anyway, remember negative marking is a factor here. Therefore, only attempt questions that you are sure of.
· Manage your time properly; give appropriate amount of time to each section. Try to improve your time by practicing as many online tests as possible. Youth4work provides online mock tests will time limit attached to each question; this way one can learn to finish the entire exam within the time limit.
· Studying in a stretch for hours can be tedious and hard and also not so good. Therefore, try to study at several times in regular sessions during a day. This will make learning easy and fun, also you will have enough time to brush up the already studied topics in between intervals. Don’t forget to practise NDA question papers of previous years that are easily available on Youth4work.com.
· It is very important to maintain proper health, so you don’t fall sick on the big day. Give your brain appropriate time to refresh itself. Don’t rush too much information into your head than its limit allows. Take it slow and steady. And get at least eight hours of sleep each night.
