Hello Aspirant,

As you had passed your class 12th in 2019 so you are a dropper and therefore your highest qualification with PCB remains 10+2/PUC 2nd and in this case you have to use code 02.

Code 03 is for those candidates who have passed their first year of B.Sc program with Physics, Chemistry and Biology/Biotechnology as their subject.
