The institute module is more than sufficient to clear the exams. Do not refer any other books for studying. Study the module very well. A lot of time has to be spent on ISCA as it is only theory. Revise ISCA on a regular basis. This is a paper where you will feel blank if you have not revised for more than 2 weeks in a row. Regular revision is required. Chapter 2, 10 is important as well as others also. Chapter 5,6,7,8 is comparatively easier to study and lot of marks can be scored from this area. Study this paper with lot of effort. ICAI require more or less you to reproduce the same from material.
