Urgent help for books ca final old course

Yes ! thats true for many. There are many books & it can be very difficult to select. Font , style also matters besides explanations given. For example, AMA book of Padhuka is pretty comprehensive. However, answers are presented in a very professional manner ,in tables etc, occupying very less space to save paper probably. Its very hard to replicate such answers by students in exam. 

Even if you may not like, sensible approach is to first refer and complete Institute study Material. Also PM for AMA. Its good for all subjects of 2nd Group. After that , you may refer any reference book of your choice. Students buy lot of books out of anxiety but due to less time or whatever , they don't even touch them. Better have very few books in the beginnning; even if it does't feel like you are doing a higher course like CA Final. Hope this helps.
