Weightage of Marks for Chemistry in NDA Exam

The NDA (National Defence Academy) exam is a highly competitive examination conducted by the Union Public Service Commission (UPSC) to select candidates for admission into the Indian Army, Navy, and Air Force. The exam consists of two papers: Mathematics and General Ability Test (GAT). The GAT paper includes sections on English, General Knowledge, Physics, Chemistry, General Science, History, Geography, and Current Affairs.

Importance of Chemistry in the NDA Exam

Chemistry is an integral part of the NDA exam as it tests the candidate's understanding of various chemical concepts and their applications. It evaluates the candidate's knowledge in areas such as chemical reactions, atomic structure, periodic table, chemical bonding, and environmental chemistry. A good grasp of chemistry is essential for candidates aspiring to join the Indian Armed Forces, as it plays a crucial role in fields like defense technology, explosives, and chemical warfare.
