Dear student,
In order to pursue Chartered Accountancy course, you just need to qualify the +2 level of examination. No matter which stream you followed and how much marks you scored in the same, if you have qualified the examination from a recognized board, you are eligible to register for Common Proficiency Test conducted by The Institute of Chartered Accountants of India. The Common Proficiency Test is an entrance test and in order to qualify it, you need to score a minimum of 50% marks. After qualifying the test, you will be eligible to register for Integrated Professional Competence Course which will be followed by Computer Training, Artcileship Training, Management Course.
Hope this might help you.
