Supriya, If you find BD Chaurasia's books more better than Vishram or IB shing's book then you must go on with that. It depends on your veiw of understanding, how you can easily cover the subject by using which book. If BD Chaurasia's books help you easily understand the concepts then refer these books. For Human Antomy, BDC has four parts: Supex, Infex, Head & Neck, Abdomen, Neuro .

Hope I answered your query, thankyou!
