Can i still receive a call from FMS with low academics?

Yes, of course! You still have a chance to get over your mistakes that you did in your past considering your Academics.
In FMS, Delhi University, they do not take academics into consideration much. So if you believe in yourself, if you’re determined to give your 100% start working hard and stop thinking.
To Calculate the final score 85% weightage is given to CAT score and remaining 15% to PI which is further broken down into 10% to interview & 5% to extempore. So try to get maximum % in CAT and perform well in PI. All the best.
