yes, its sufficient. i had refered OTM for six subjects and easily cleared the exam with 58%..

ALL the Best..

hey better to go with reliance publkication books coz in OTM you will get more theory but in reliance book u will get the theory aswell as past 25 exam GLA(guide line answers recomended by the ICSI) just go through it and no need to refer any other bookj even the study module..........................

I will also suggest only this much Book, as i also read and got good marks..
