Reg. Group-I, I advise you to first try to cover all the practical problems given in accts, cfm, tax and then refer practice manuals, suggested answers and revision test papers, which are available in icai website for download. If you are confident upto these, then you would have covered almost 60% syllabus. For theory parts, I advise you to study theory only from inst. module for subjects like ethics and communication, service tax and vat; financial management and costing(for cfm questions covered in practice manuals are almost sufficient, after referring them you refer other theory questions  in inst. module). For tax, you can refer Girish Ahuja. If you have already prepared for 2nd group earlier, then go for both groups, other i advise you to go for single group again confidently. For Law, you refer Munish Bhandari, which you can refer fastly, as it is bullet-wise answer book. Make sure you keep 1month time for revision of all subjects again of whatever you did as above.
