Pm or not?

Please tell that whether to refer Practice manual or not for ca final audit ,as i am studying this very subject from Surbhi bansal's book and her class notes;keeping in mind that my both groups are due in november 2012.

And please also tell the same about Corporate and allied laws which i am studing from munish bhandari's handbook,that along with this book should i refer Practice mannual or not(on the basis of limiting time factor)
