Hi Arjun!
The recommendation for books may vary from student to student. If a student prepares for the exam just one day before, then the recommendation is to purchase ten year question papers with solution. It will be easy because students get an idea about the type of questions asked in the exam.
But if you revise and study the subject on a daily basis then try one or two sample papers of a particular subject. This will increase your confidence and you'll definitely score great marks. Moreover, you can study deep from books like :-

• Fundamentals of Statistics by S.C. Gupta and V.K. Kapoor
• Cost Accounting Principle and Practice by S.N. Maheshwari and S.N. Mittal
• Management Accounting Principle and Practice by S.N. Maheshwari and Mittal
• Adhunik Bhartiya Company Adhinium by Kushal and M.C.
• Corporate laws by Kucchal and M.C.
