I think, on the basis of graduation direct registration is not possible, you must do PCC.
A student who has passed Common Proficiency Test and Senior Secondary Examination (10+2examination) conducted by an examining body constituted by law in India or an examination recognized by the Central Government as equivalent thereto may join the Professional Competence Course Simultaneously, the student will also register for practical training of 3 ½ years In addition, a student has to register and undergo 100 Hours Information Technology Training after completion of 3 months of articled training.
