CA final audit & ISCA paper

ISCA - Manish Valechha - all study tips are given in the book, it gives you mnemonic codes to remember the points.. (best seller ....and much better than dinesh madan),, 

Audit - Pankaj Garg (much better than surbhi bansal as it covers practical/past exam ques. and is exam oriented) Surbhi bansal is easy but you cant fully rely on it 

Refer Practice Manual for practice and IMP Questions.

Dosto Sabh chod ke sirf isca module through revise with each points even in boxes and first start preparing from small chapters and in case of audit refer v.k. aggarwal and icai practice module

Plese Also suggest me how to prepare for ISCA and from which Book.... and also for Cost and  QT.

Plz also suggest me which book should i refer for ISCa and how to study this subject. and also Cost and QT. thanks

U may refer ISCA by Vishal Saraogi (Law Point Publications) - I found it quite friendly
