Hi, congrats for passing IPCC There will be changes in indirect taxes and ISCA syllabus which will be applicable from Nov 2014 exams. The updated syllabus is already available in ICAI website. Regarding company law you can leave it for now and start reading other allied laws till ICAI brings the updated study material. You can start your preparation with practical subjects like AMA and SFM. Since your attempt is May 2016 you can keep yourself updated in the meantime through RTPs and supplementary study material. Our Institute study material published online contains the date of update and also changes in the current edition. Hence whatever books you intend to follow just keep track of the changes in syllabus till your exams. In this way you can prepare well for theory subjects too.
