Hi there. 

Your qualification code would be 2 if you aren't pursuing B.Sc. 

If you have completed B.Sc then code would be 6 and if you are in 1st year code would 5.

CODE: 02

A Candidate who qualifies their Higher/Senior Secondary Examination or the Indian School Certificate Examination that is equivalent to 10+2 Higher/Senior Secondary Examination after a period of 12 years studies. They have to complete their qualifying examination with Physics, Chemistry, and Biology/Biotechnology (that includes practice tests in the given subjects) and Mathematics or any other elective subject with English at a level not less than the core course for English that is prescribed by the National Council of Educational Research and Training after introduction of the 10+2+3 educational structure as recommended by the National Committee on Education.
