No, you cannot get IIT. But, there is still a chance that you would get an NIT.

If you belong to general and OBC then there is no chance that you get good government College, but if you are EWS or SC ST Candidate, you can get govt college.
But the placement criteria are not good
Hence you should apply for a private college. you will definitely get good college and also get a scholarship.

Based on the information you have given, you have fewer chances of getting into NITs. However, you can try getting admission into government colleges in your state that accept JEE scores. For instance, some colleges in Telangana, Karnataka, and Rajasthan accept JEE scores.

If you're a general category Delhite, then there's no possibility that you'll get the admission in DTU in any branch. But considering that you have mentioned quota, I want to know which quota to explain better
If you fall under OBC category then yes you have the chance of getting admission with branches lower or equivalent to electrical engineering
If you're SC or ST, then accordingly you have the chances to get admission with better branches.

As you know the percentile depends on various factor like number of students in your shift, the question paper difficulty level, and the students level also. From the previous year cut-off trend, you should have 99.25 percentile to get CSE in the NIT Kurukshetra from home state. And it also depends on your category from which you belong. So revise regularly and prepare for the exam and you may get your choice.

If you ask about Computer Science in India: IISc. Is the only place. Rest are just selling what is required by market. They are packaging tea on the wrapper of coffee. Well, this has been always our habit, so we are paying for it. We hardly have any product of our own in field of Computer Science. And then you can find your career in better way.
