I am sorry to say that it might be quiet difficult to get into a good college, and doing masters is not worth doing from a good one. I will be following this question to see the response from experience as I am also trying (Marks: 48.67 as per predictor: https://gateoverflow.in/mymarks) to get into a good college.
Furthermore, it would be helpful if someone will list out the available options to save a year. I would be really thankful for the same.
Available Options as per my point of view (ISI C, IIIT H, BITS-P, IIIT Alahbaad, Bits Hyd/Goa, DTU/NSIT, CMI )
