Masters

Hello Akash Singh,
Many deemed to be universities offer integrated BTech+MTech programmes. Many a times of five years duration. It's a great offer since there is no hunting for admission to PG and also in one year less two degrees are obtained. However one does not have chance to choose subject for PG. It's the one decided at the time of getting admission.
Best wishes to you.
