Hi Soumil, 

Most of the colleges in India provide a dual degree course where they give the student the degree of either MBA or M.Tech( The choice of student), In 5 years the students will have 2 degrees which normally takes 6 years. Now, In NIT Hamirpur, the engineering students are given an option to either take a 4 year course or a 5 year dual degree course. To take that decision, you must ask yourself these 2 questions:

1. Do you want to do M.Tech after your B.tech and go to research field.?

2. If yes, then would you rather complete your M.tech from India or would like to go abroad for further studies.

Now, if you think that you can study 5 years, with a chance to go for research sector. Then go ahead and take the dual degree course. But , If you want to take up a job after your B.tech then go for 4 year course and you may complete your MBA or Mtech while doing job or after a 2-3 years experience. 

In NITs, Both the 4 year and 5 year courses are good. So take above factor in account while choosing.

So Best of Luck,

I hope I was able to clear your doubts.

If you have any other queries then do post it on the portal

Thank you
