Hello aspirant,

No, you can't change a subject in second year of BA , but you can change your honours subject from one of your core subject in 3rd year of BA.

Furthermore, if you have backlogs in your graduation years, then it will make you more difficult in changing subjects in second year.

Further, to know more about the BA course complete details, you can follow the below mentioned link to know more about it : https://www.careers360.com/courses/b-a-bachelor-of-arts

I hope that this will help.
