Costing theory- ca final

Studying on selective basis is self-destructive, it is not safe to skip something or study only a few specific topics. In a professional exam like CA you may know even in QT / OR questions are framed to know the conceptual understanding of the topics and no direct questions are asked. I know you have shortage of time on hand, but there is no substitute to your hard work and efforts, and my sincere suggestion is not to go with a selective approach.
