Please advice

I am appearing for IPCC group 1 in nov 2011. I have finished the four sujbects to the extenet possible because i am working proffessional and to be frank i get time only on sat and sun to study. So i thought of practising Revision Test papers and past question papers and if i have doubt i can refer back to books Will it be helpful for me or should i have to complete the whole chapters from the subjects and then go for RTP and Question papers. Please advice ??
