Hey

National Defense Academy conducts it's exam twice a year; NDA (I) and NDA (II). The 3 parts of the exam are:

• Mathematics
• English
• General Awareness

Therefore, you must revise and practise 11th Mathematics and keep doing good in 12th Mathematics as well, as Mathematics holds 300 marks and the candidates need to score qualifying marks in it to proceed further as well.

For English, you can go through any of the standard books like Wren Martin or Word Power made Easy by Lewis.

General Awareness has the highest weightage, so read newspaper daily and keep a record of all changes and highlights of the year. You can also refer books like Pathfinder for NDA.
