Plz help i m science student n preparing for ipcc

Have you done cpt (formally or informally) accounts? or are you entirely new to accounts?

Take one of those fat university books like shukla grewal, chakraborthy, haneef mukherjee etc and do indepth study. If you don't have the basics right it will be always a struggle. PM me if you need further advise. 

As per my opinion    full practice mannual and all coceptual problem of study matterial are sufficient for ca ipcc . . for more practice you should refer paduka (mainly you use paduka for solve problems).

and also refer rawat (ipcc addition) for better understanding of AS .

sorry, I disagree. Don't refer padukas. It's just a bunch of problems. Not for concept building. Maybe for practise. It's from a tuition centre. Good for students who attend those classes. Not for self study.
