You must have a master strategy for clearing ipcc.First thing comes the "resources"
You cannot depend on ICAI SM(Study Material) for each and every subjects.Here is what i prefer.
1.Accounts-ICAI SM and PM(Practice manual)
2.Law-Vijay Raja Authored book. get it at https://www.amazon.in/Business-Laws-Ethics-And-Communication/dp/9795368788
3.Cost FM-ICAI SM and PM(PM is must)
4.Taxation-ICAI SM and PM(as indirect tax syllabus is fresh many question in EXAMS are coming directly coming from PM as far as i have noticed)
5.Adv Accounts-ICAI SM and PM(PM must)
6.Auditing-I would personaly say NO to ICAI SM.Refer any good scanners at https://www.flipkart.com/auditing-assurance-ca-intermediate-ipc/p/itmeyv2cbygjuhy6 and be good at companies act.Rest of auditing is General(Vouching,Special audit stuff) and even in Q#2 of EXAM some 10 q are like bonus.One can score easily in True or false)
7.IT-Sm
- IT-ICAI SM and PM
- SM-ICAI SM and PM
- One need to see the past questions from this paper and prepare SMARTLY

NOTE: I also Personaly prefer ACCOUNTING STANDARD MADE EASY authored by CA Ravikanth sir. It includes both G1 and G2 AS.Simple explaination with "Concept capsules"
You can get the book at https://www.amazon.in/Accounting-Standards-Made-Easy-2015/dp/9351392414/ref=sr_1_1?s=books&ie=UTF8&qid=1436368603&sr=1-1
HOPE it may help our future CAs
ALL THE VERY BEST .
