You are advised to appear for JAM (Joint Admission Test for M.Sc) for seeking admission in M.Sc in IITs.

If you are only concerned about placement then go for IIT mandi CS, but if you are interested in other things and your overall development because at last money is not what you want, go for Physics, IIT delhi or Mech, IIT roorkee.

First of all congratulations! I will recommend you to go with CSE from IIT Mandi, but in that case only if you have a keen interest in computer science and engineering. Placement wise it's very good also you will get very good exposure. IIT Mandi has very good semester exchange program too, you have a very good option there to go abroad and explore further. Else if you wish to go with core opt for the other options which are left.

That is based on your interest solely. I would suggest NSIT CSE as IIT Bhubaneswar is a new IIT and textile at IIT Delhi would not get that many placements in the sector. If you want a well-established college culture and willing to discover your interests, go for IIT Delhi. But know this, that you will have to make your own way, be it coding or any other job.

No, you can not enroll for any B.tech program at IIT Delhi in any way other way. The eligibility criteria is to qualify JEE mains and advance.

First of all congratulation for getting a decent rank in JEE Advanced.
Now you should decide which branch you want to pursue. If you are interested in civil then you should surely go for IITD. If interested in metallurgical branch, then go for IITB and if still wants to do mechanical, go for Roorkee.

These numbers are never revealed. And also, this number keeps varying year by year. Sometimes it can be high and sometimes it can be low depending on how many students were able to grab those consult/tech jobs which usually pays higher than textile core jobs.

The best order is the only one for you.
