NDA Chemistry Analysis

In short, Chemistry deals with chemical bonds, properties, and change of matter. Even though it is not the easiest subject to study, it can still be one of the top scoring sections in NDA exam. Chemistry section falls under Part B of Paper II. It tests the general knowledge of a candidate in the field of chemistry.

Detailed Analysis of Chemistry from NDA 2016
