Hi aspirant,

There is a correction window which is opened for a brief time period for candidates to edit their personal information and other details. So I dont think it would be possible for you to change it during that window. Now coming to the next possibility of applying again then I want to tell you that a student cannot apply for both B.des and B.ftech at the same time. It was allowed before 2016 and now its not possible as both the exams are conducted on the same day.

However you can definitely appear for bftech if you haveMaths, Physics and Chemistry as your subjects.

Hope it helps!!
