dear preeti,

since you have not passed your bsc course and currently you are in 3rd year so your code will be 05.

code 05 belongs for the candidate  who has passed the first year of a bachelor's degree from a recognised university with Physics, Chemistry, BIology/Biotechnology inclusion of practical tests. Candidates should also verify that the first year exam qualified is a university level exam and they have also qualified Class 12 qualifying examination with the said subjects at a level not less than a core course.
