well u should take up undergraduation in India as the course level is same around the world and u would get good education at less rate here .Later then master studies u can opt from outside as the difference lies there as outside they spend huge in research and other stuff.

No, you won't be able to get into the college because of your low marks in JEE Mains exam. Even though you have scored really well in the HP Board exams, you would need to get more marks in JEE to get into this college. Also, please specify the branch you want to get into so that I can tell you the cut-offs of that branch. You will need to score around 150 in JEE Mains to get a good branch at NIT Hamirpur.
