Hello, 

You can fill the qualification of 10+2 only and because you didn't complete your first year then it is ok to fill the 10+2 only . And also remember that according to the eligibility criteria of neet your age should not be more than 25 years and also you shusho have 50% marks in all the three required subjects.

Dear Shubham, in your case as you have completed your +2, your qualification remains +2. Though you are pursuing your graduation, as this is still incomplete, you should fill in the code of +2 which remains your highest qualification. Do let us know if you need more information. Good luck.
