AUDITING
Must go for new compiler for AUDITING its very good I must say and for SAs Surbhi bansal mam's book is the best.
LAW
For Law munish bhandari both handbook and main book... Must do each and every practical question from main book as final paper is 100% practical...
MICS
For MICS I must say whatever u refer u must go thru the module first thats sufficient and u must take a look at NOV 2009 and May2010 RTP questions for MICS as they have been practical oriented questions ALL THE BEST...!!!!!!!
