With reference to the Accounting paper(s) of PCC/IPCC -
The two volumes on accounting by Dr. BM Aggrawaal & Dr. MP Gupta are good for building a good conceptual & theoretical base. If you're interested in solving more problems then you can go for Dr. PC Tulsian's two volumes on accounting, but beware of its theoretical portion as it's too confusing; try avoiding its theory.
My recommendation is based on my personal experience.
