Hi Saurav
First of all congrats on your clearing the CPT exam. Below are the answers for your queries as per my view:
1) As you have passed CPT in December 2010, there is a notification in the ICAI website for the CPT passed students to register for IPCC before January 2011. You should need 9months study gap in order to write your IPCC exam in November 2011. So I advise you dont delay now anymore and immediately take the application form for IPCC and fill it up and send it to the required address mentioned in the application depending on your South/North/East/West regions.
2) Regarding the exemptions, I didn't heard any exemptions for CPT passed students in further exams. Can you clearly specify what exemptions your friend has told?
3) To join IPCC, no 15 months training is needed. You may have seen some old information. To join in IPCC, you should be CPT passed student. Articleship of 3 years in CA will start after you clears the IPCC First Group. You may also choose to write both groups of IPCC at a time. But First Group should be cleared first, which makes you eligible to join for articles, which will then goes on for 3 years.
4) In my application, I have filled for both study material and I also chosen Both Groups with Articles option. So fees should be paid accordingly for Both Groups with Articles. If you wish to register for only Group-I, you can do so. But regitering for both groups and preparing and giving for both groups at a time is advisable as you have time to study. If you feel you cannot be able to complete both group subjects in this 9-months period, you can write only First Group Exam. However, while filling up application, you pay the fees for both groups and take the study material at a time, later on its your wish whether to write both at a time or single each. You have the choice of selection even you paid fees for both groups. In my view both groups with articles fees is around 12,000/-. So you check before you take the DD after considering your exemptions of fees.
5) However, in your case, as you are handicapped, there will be fee exemption in case of Orientation Programme of (Rs.4,000). The exemption notification to handicapped students given by ICAI is given in this link (https://220.227.161.86/20166announ10965.pdf). You can go through it for your reference. So, in your case you are exempted from payment of orientation program fees and also for attending the orientation is exempted.
Regarding the ITT Program as per ICAI notification ITT is to be completed before registering for articleship. However, it is advisable to do ITT in your 9-month period.
6) There are some differences between PCC and IPCC. However, registrations to PCC is not allowed now, so you must register for IPCC and concentrate on IPCC syllabus itself. IPCC is the latest scheme as of now.
Hope above answers will suffice your queries. By the time you receive your IPCC study materials, you can download the soft copies of the study materials of ICAI from this link (https://icai.org/new_category.html?c_id=314). All the best.
