Hey viva

No , Fluency In English Does Not Effect Your Du Life . In Fact, Be Yourself , People Will appreciate That . Because In Du , There are Many Students From Each Corner Of India. All You Have To  Do is ,be Yourself And Represent Your Self Confidently. Students In Du appreciate That Alot. Besides , Du Life Is Much More that Than Fluency In English , It Does Not Matter That You Speak English or any other Language , Just Be Confident And Enjoy Your Du Life.

I Hope It Helps

 Good Luck 

dear candidate,

Fluency in english is something that can be picked up when you are with people who speak english constantly. Delhi university is like any other place for study and yes you may have an added advantage in presentation but in social life if you are forthcoming and any easy person then spoken english wont matter much.
