First of all Congratulations for qualifying GATE. Now come to collage IIT Jodhpur has good placement record and you obtain one tag mark "IITan" then come to NIT surat and Surathkal. that preference is according to placement .

Hello,

As you want to do Mtech, so overall all the mentioned colleges are good. But comparing the quality NIT surathkal would be at top among these three. Although there is IIT but IIT jodhpur is not as good as NIT surathkal. Placements are also very good here.

All the best.
