GENERAL KNOWLEDGE
General Knowledge including knowledge of current events and of such matters of everyday observation and experience in their scientific aspects as may be expected of an educated person who has not made a special study of any scientific subject. The paper will also include questions on History of India and Geography of a nature which candidate should be able to answer without special study.

Paper 2 in NDA i.e. the General Ability Test judges a candidate’s basic awareness and English proficiency. This section is further divided into two parts, English and General Knowledge.
Part A- English
The English portion of the entrance test is designed in a way to judge a candidate's knowledge of the basic grammar and vocabulary.
It judges a candidate’s ability to form correct sentences and use of words.
The syllabus of the English paper ranges from various aspects like the knowledge and usage of grammar, vocabulary, comprehension, and his mental ability to remember and place the meaning of words in their proper places.
Marks allotted to this section are 300.
Part B- General Knowledge
The question paper on General Knowledge will cover current affairs, questions from Physics, Chemistry, General Science, Social Studies, Geography and Current Events.
