IIT Dhanbad (ISM) - Indian Institute of Technology (ISM)

To get admission in B.Tech, the minimum eligibility is 60 %. You need to clear JEE Mains and Advanced to get admission in IIT.

May I know your GATE score and rank?

It's better but first qualify GATE so that it would be better you to join in any government sector. Nowadays many government sectors are making GATE as the qualification for them. M.Tech is not that useful. Go with government jobs preparation.

IIT, Dhanbad admits its undergraduate student's through Joint Entrance Examination (Advanced), previously-JEE. Admission into IIT Dhanbad is a two-step process. One needs to qualify JEE Main and then give the JEE Advanced. Admissions are based on the JEE Advanced rank.

First, it depends on your interest level on the Branch. Next, is the duration of course. Are you okay to spend around 5+ years in the same course, and specialization at a stretch? If you are inclined to take up career in IT and Data-Science, Machine learning etc., then better opt for integrated course. ECE will be a bit tough, when compared to IT, and if you are very keen to go for ECE related jobs, then you can opt ECE from ISM. Keeping in view of placement opportunity and coding environment, it would be better if you to go for IIIT integrated course.
