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

First thing first – Smile, you still have a chance to make up for the mistakes you did in your past (acads). FMS, Delhi do not take academics into consideration. So if you are determined to give your 100% (as you said) stop thinking and start working hard.
For calculating 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
