Back Your Strengths 

Always back your strengths. Every individual has their own strengths and weaknesses; back your strengths and try to utilise them maximum. For example, if you are very good in Maths, Physics and Chemistry, try to maximise it as each and every mark will increase your chance of clearing this prestigious exam.

Practice NDA Previous Year Papers

Solving NDA Previous Year Papers one week before the exam normally tests the consistency, nerves, intelligence, and all the hard work you have put into your preparations. Treat these PYPs as your last few rehearsals before the actual exam. Manage the sectional time effectively during the test. This practice will help you utilise the time during the actual test. Always take the complete PYP in that exam time slot only. This will keep your body and brain ready for that particular shift timing and enhance your performance on the exam day. 

Analyse Your Performance

After solving each PYP, analyse your performance and note down the areas of improvement. Identify patterns in your mistakes and work on wiping them out. Time management is crucial for success in the NDA exam, especially in the mathematics paper, so pay attention to it as well. 

Work On Your Mistakes

Focus on the mistakes you’ve made while reviewing your past performance and try to fix them. But don’t start learning any new topics now. Just revise what you’ve already studied and try to avoid making mistakes in those areas. In the exam, you’ll need to do long calculations in a short time, so it’s important to keep your speed and accuracy high. If you’re making calculation errors, work on improving that right away so you don’t lose marks because of it.
