Yes you are correct almost every question and answer are different, if you intend to score good marks then you need to put extra effort in understanding the subject more conceptually than mugging up.

Dear Umesh, Cost and FM is one of the scoring subjects of CA-IPCC. You need to ensure that all concepts are thoroughly clear and only then you'll be able to solve different type of questions. My tip : Cover Practice Manual completely along with other reference material. Do not leave theory for the last few days. Generally it is a lengthy paper, so solve 2 or 3 mock papers before your attempt for practice. All the best!
