As you got only 41% marks,I don't know whether you can register for CA because only the Commerce graduates with 50% marks, non-commerce graduates with subjects other than Mathematics with an aggregate of 55% marks and non-commerce graduates with Maths with an aggregate of 60% marks are permitted to register for Integrated Professional Competence Course (IPCC).
