Hello aspirant

You should fill code 2 if you have passed and results are out.

NEET 2021 examination code 2:

• Candidates who have completed a period of 12 years under Higher/Secondary examination or the Indian School Certificate Examination (ISCE), which is equivalent to Class 10+2 can opt for code 2. However, the last two years of study must include English, Physics, Chemistry, Biology/Biotechnology, or Mathematics or any other elective as a major subject as prescribed by the National Council of Education Research and Training (NCERT).
• Aspirants who have passed 10+2 from the National Institute of Open Schooling (NIOS) or state open school, as a private candidate from state boards; with Biology/Biotechnology as an additional subject can apply under NEET qualification code 2.
• Who can also apply code 2: It should also be noted that the qualifying examination code for NEET 2021 for droppers will also be the same. For instance, a candidate has passed the qualifying examination from CBSE/ISCE or any state board in the year 2018, but wish to appear for NEET 2021, he/she can apply for the exam with Code 2.

Above is the explanation who can fill the code 2. So you are also applicable for code 2 as you have passed the 12th exam.

All the best
