Dear Neeraja, if your highest qualification remains +2 with Physics, Chemistry, Biology/ Biotechnology, then your code is 02.

According to NEET website, 02 is for those candidates who qualifiy 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.

However if you have started B.Sc, then your code changes. Do let us know if thats the case.
