i passed my class 12th examination in 2018,i took 2 years drop which code whould i use?

Hello,shreya you will have to choose CODE 2,

Which states that-

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 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 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.

Thank you
