Hello student ,

As you mentioned that you top four subject score is 78% and you want to change your stream from science to art then It will be quite difficult for you to grab a seat in delhi university college.

Because when you will apply for BA then they will deduct your percentage by 5 and you will get to go for seat there with 73% marks.

So, If you are from some reserved category then it will be easy for you to get a seat in some du college.

Hope it will help!
