Hey student,

Inorganic chemistry remains as one of the most easiest part of the jee adv examination. Generally they ask questions from the common ioc topics. Yes, they can blend inorganic with physical/organic to complicate the question.  NCERT is enough for 90% of the inorganic questions. But for the rest of the 10% you need not to use other reference books; instead you must have the capability of finding the answer through the application of multiple concepts.  Cover the important chapters line by line and try to understand it.  First go through the proper syllabus of the jee adv, then choose a chapter one by one and finish it.

All the best student,

Hope this helps you.
