But there are few things which should be kept in mind as ICSI has started giving very fewer results.
1) Patience- It is the key to success at least for CS executive exam.

Some tips for preparation
For CL, ECL, SL and IGL- Just read the chapter and try to understand the concept of each and every topic. Don't mug up things it will result in nothing. After that, make notes in such a way that you end up summing up the entire chapter in one or two pages and revise it in every 15 days. THIS SERIOUSLY WORKS. For the cost- practice the questions from NS. Zaid as 90% pattern of the questions is same as asked in the exam. For tax - practice questions of BANGARH and give equal importance to all short chapters as sometimes they end up asking 50% of questions from those chapters. For Accounts-Treat audit and accounts as the different subject and follow the same strategy for audit as followed in other law subjects and for accounts practice module and give equal importance to theory topics.
