ICAI

Hi Aniket,
You don't have to worry, as to apply for CPT exams one has to clear SSC exams i.e. 12th Class.
CPT Exam is held twice a year i.e. in month of June and December. Therefore, to appear in June exams- a student should have applied for CPT registration before 1st April and to be eligible for December Exams- a student should have applied for CPT registration before 1st October.
To be eligible to appear for CPT Exams, a student should have cleared/appeared for Class XII Exams. In case the Results of Class XII has not declared at the time of registering for CPT, the student can apply for provisional registration and such students would have to furnish an attested copy of their passing certificate with ICAI on clearing the Class XII Exams.
There is no condition regarding the minimum marks that should be scored in class XII Exams and everyone who has cleared the same is eligible to apply for CPT Exams.
For more details you can refer the official site.
Hope it helps. Please feel free to revert.
Wish you luck.

ICAI (Institute of Chartered Accountants of India) and ACCA (Association of Chartered Certified Accountants) both are Chartered Accountancy body but there is huge difference between both.
ICAI members allows to perform audit and other related function in India. While in case of ACCA, it is not recognized in India. ACCA gives global exposure but it has no value in India as compare to CA(ICAI). Unless you are working with Big4 or MNC. ACCA is mainly accepted in Gulf, European and Southeast Asian courtiers.
So if you are planning to choose any one of them then you have to consider where you want to go. If you are planning to stay in India then CA is better then ACCA. For other countries, ACCA is better. Also, if you are Indian CA then you have to give only 5 papers.
Since both have different geographical area you have to choose accordingly.
