FR and SFM book

Books for the CA Final Old Course by Prof. Rahul Malkan are out of print. Your best options are searching for second-hand copies on student forums like CAclubindia, checking specialized used-book portals, or looking for digital study notes on educational resource websites. Always verify the applicability of older books against the specific syllabus requirements for your exam attempt.

For Financial Reporting (FR)

- The ICAI Study Material is your main reference point. 
- Some good references to consider if you would like are Praveen Sharma notes/books,M.P. Vijay Kumar, and Aakash Kandoi materials. 

For SFM/AFM:

- The ICAI Study Material and the Practice Manual should suffice to cover what you need regarding the exam. 
- There are also many reference books, such as J.B. Gupta and S.D. Bala, which have been used by many students. Also, there are many faculty notes available from established coaching teachers.

My Advice: Use one faculty notes + ICAI Study Material + RTPs/MTPs. Do not use multiple references for the same subject, as it often creates confusion when revising.
