Dear Pranathi, Code 05 is for Candidates who are in their 1st year of B.Sc and Code 06 is for those Candidates who have completed their B.Sc. These codes were brought into picture in lien with the age limit. Now that the age limit criteria has been out on hold, the nearest code that suits your qualification is 05. Atleast in a way this code denotes that you are still pursuing your B.Sc than 07 which denotes that you completed your B.Sc.

Code 05: Candidates who studying in the first year of the three years’ degree course of a recognized University with PCB (that includes practical tests in the given subjects) provided the examination is a University Examination. The candidate also passed their earlier qualifying examination with Physics, Chemistry, and Biology/Biotechnology with English at a level not less than a core course.
