Hello Ayush,

You may study by looking up the internet for global art, it’s history and important trends as there is no single book. for visual art, you may study Partha Mitter’s book Indian Art, Dances of India published by Vivekananda press, critical essays by Kapila Vatsyayan and Ananda Coomaraswamy on Indian aesthetics. Better to study from the factual perspective as the exam will no longer be subjective and would not require a critical approach.

Hope this answers your query, feel free to ask for more info.
