Hey Nayna.

See the marks su have scored is not that pretty much enough for u to bag a satisfactory seat in the good college for pusuing ur higher studies in the field of ur interest. U should be going for some private institutions for ur mtech career which accepts the low score of the GATE exam. I can also provide u a predictor which might help u in some way.
