Hi there!!!! If you wish to do Mtech then it is really a good option. It will save your one year and will be able to graduate from a NIT which is again good. NITs have good reputation and there is definitely scope in whatever you do in college provided you work very hard for it.NIT will open a lot of doors of opportunities for you. It is up to you if you can take advantage of it and work towards it. To summarise , if you are determined and sure that you work off hard those 5 years,then it is definitely a good carrer choice and there is certainly scope in it. So believe in yourself and go for it!! Best of luck!!
