Respected sir,

For OBC category, upto AIR 40000(GENERAL RANK) , people get in NITs. And for that rank marks of around 150 & CBSE BOARDS % around 91-92% is needed. As ur marks increase u require less borads % and vice versa.

Thank you.

Hello buddy,  According to previous year cutoff you can get ECE at Nit jalandhar if you have Punjab quota and similar or lower branches according to the Ranking and cutoff of the NIT.  If your home state NIT is new NIT than you can get CSE in it and if it's top NIT than you will get lower branches. To get brief information about your college you can use career360 services. 

Best of luck buddy. 

congo for crossing the exam,with your marks you can get into a nit but not a good one according to me ,so it would be better for you to look for other colleges or else if insist on nit brand you can go for it as ultimately your choice so all the best.

Yes, you have chances to get NITs based on your marks/rank.
