About eligibility of ca course

Hello Sir, I am a final year graduation student. I am studying B.Sc. (maths). I will pass my graduation in 2016. I want to know that if i am eligible to register for CA-IPCC under "direct entry" ?? Also, I have heard that syllabus for CA course has changed and it will be applicable from 2016. So, if I register now in 2016 shall I be under new changed syllabus?? Also, as per old syllabus. there are ITT & orientation, we have to complete before commencing articleship but according to new syllabus, we have only one ICITSS. So, please explain this. and most important what is the articleship scenario for science graduates?? and when will be my IPCC attempt if I register in 2016.
