T.y.bcom & ipcc

I m ty & ipcc student. I m going to appear for both groups in nov13. I have my ty half yearly board exam starting from 21st to 30th oct & ipcc starting from 6th nov. Im now studing for my ty exam n did only little preparation for ipcc gr 1 from practice manual & RTP NOV 13 as I thought I would clear both group in may 13 exam (so dint not study before results) & not touched gr 2. I think I will manage to complete my gr 1 studies after ty exam(PM+RTP NOV 13).My question is just doing Practice Manual & RTP NOV 13 sufficient to pass ipcc exam both grs? As in my earlier attempts I used to do only my classes notes but it dint help me in exams as questions asked in exam are of different type & I found similar type in pm & so this time I m not doing my classes notes.SO PLS REPLY WHETHER PM+RTP NOV13 SUFFICIENT TO PASS OR I SHOULD DO ANYTHING ELSE ALSO & WHAT?
