To be frank, before the exam read the ICSI material for CMSL atlest 4 times, it helps and to write the answer use better English rather than reproducing the matter is same language.
It is a very vast paper.Read the whole module properly atleast twice.Important chapters to be thoroughly revised.Eg: Issue of securities. Reference books can be used for previous questions and answers.Remember....write upto the point.
same problem here, but what I am doing is studying thoroughly module and studying question and answer from taxmann CMSL book, it's really a good book it contains more than 1000 question and answer, even you can also purchase this book. Good luck
