For TUM, GATE score should be high enough. But writing only GATE is not enough, you have to write GRE tougher and trickier than GATE to study abroad.

For Master's degree, you need to have cleared GATE and in college like RV, they ask for high scores for the same.

Regret to inform you that, you will not get any seat in NIT, Warangal because in order to take admission in NIT-W one must attend a nationalized exam and also should clear the cut-off.
