Indian Institute of Technology, Delhi

Yes, you can get IIT, Delhi if you have a good rank.

Hi,
The marks required to get admission will be a very tough thing to tell, as admissions are rank based and the marks fluctuate every year both in percentage as well as absolute due to varying difficulties of the JEE each year. You can check the relevant ranks and other data on JoSAA website. It is the most reliable resource as JoSAA is the body that sees the admission process through JEE. http://josaa.nic.in/Result/result/OpeningClosingRank.aspx.

You must have rank under 100-150 in your category(ST). Score stats are different every year since the paper pattern is not fixed. But you should have scored atleast 45-50% marks for that.

Yes, you are eligible. The IITs accept all graduates.

No, the government college doesn't offer direct admission through management quota, but you can take admission in private university.

I don't know about CEED, but if we get in UCEED we have chances in IIITs.
