Hello, The Institute has already made the students informed about the Subject in which changes has been made. It also has made clear the Old Syllabus students will get the sufficient no. of attempts to clear their exam. So you need not worry about the new syllabus just focus on your old syllabus and get clear your exam.
The new syllabus has been launched by the ICAI but the same is yet to be implemented by the government. Till the same gets implemented the old syllabus will be in force. Even after the implementation of the new syllabus, the old students will get enough opportunities to clear the exams based on the old syllabus. So you do not need to worry as there is no change in the syllabus as of now and the same will be applicable for May,2016 exams.
