           Tips To Crack NDA Exam  

•  Prepare yourself :- Friends there is well said by Alexander Graham Bell "Before anything else, preparation is the key to success". You should solve sufficient problems of each topic from a reference book.We all undoubtedly have the will to get good marks, but together we should have the will to prepare to succeed in order to make it happen.                                                                                   
•  Get A Good Book :- Practice makes man perfect. you should practice some questions from new edited book. It will help you a lot. you will get confidence. You will know the pattern and difficulty level of questions asked in exam. Things will get better.  prepare for maths, physics, chemistry, biology from 11th and 12th book.                                                         

•  Solve Previous Year's Question Paper :- Solve previous year's question paper. You will get an idea which type of questions can be asked. you will understand exam format and pattern. point out important topics on which most of the questions are asked and predict which type of questions will be asked.                                                                                            

•   Maintain Your Speed :- Your speed is most important in any exam. If you maintain your speed, you will be able to solve most of the questions in given interval of time. You should read the question, understand what is asked and find the answer as fast as possible. According to my experience,we can do it only when we have much knowledge about that question. In mathematics, you should know formulas and shortcuts perfectly. And if you don't, you will have to spend much time on that question. Generally most of the mathematical questions are long, so it will be better if you learn shortcuts. Do most of the calculations mentally. It will save your time as well as do not occupy space. As small space is given on question paper for calculation.                                                                                                   
•  Solve Easy Questions First :- As soon as you get paper, start solving easy questions. It requires less time and you can earn more marks. Do not stick to the difficult question, it wastes your time. Instead turn around and go to other one. You should try it at the end of paper.                                                           
•  Stay Update :- Stay aware of current affairs. Reading News papers, Magazines, General knowledge books(updated), watching news on T.V. can make you up to date. This is important section. Questions will be asked on this section.                                                                                           
•   Make Your English Good :- If your English is good, the PART-A of Paper-II will be so easy for you. You can score well in it and can save much time for PART-B. The best way to make your English perfect is reading English books. If possible make the atmosphere around you in English. Watch English news, read English News paper, Listen English songs, etc. Learn English words everyday.                                   

•   Make Your Known Topics Perfect :- If only few days are left for exam, then concentrate only on those topics which you have better knowledge. Do not jumbled your mind by reading unknown topics(specially Phy, Chem, Math).              

•   Be Confident :- Some students study hard day and night, but could not get good marks even though they know answers. Believe in yourself and your abilities. If you have confidence in yourself that means you believe that you have the ability to do anything. Confidence overcomes the fear. Lack of confidence results in attracting negative thoughts, negative feeling from your surrounding. So while exam stay calm and confident.
