Please suggest good book

I would suggest you to study from the module only....it is pretty concise & relevant for the examz....

I have already appeared for the 1st group in June 11.....like you, even I was searching for different books ...but, in the end, the module proved to be sufficient..

One more thing that gave me a lot of help was the Suchita prakashan scanner....It has some pages in the beggining that contain the summary of the respective acts....this was also very useful...this feature was available only for Law(....atleast amongst the 1st grp)...All  the Best!!!

YES MODULE IS SUFFICENT AND GOOD.

STUDY PRACTICE MANUAL ALSO,YOU WILL GET MORE GRIP ON SUBJECT.

@ Shankar : Is there a practice module for CWA also ??? I am totally unaware about it....

I THINK ITS NOT AVAILABLE BUT IM NOT SO SURE ABOUT IT.
