Hi,
As you have scored 82 percentile in JEE Mains and your CBSE board marks is 70%, so you are eligible to take admission in Delhi in IPU. You will also get the benefits of Delhi domicile. So, just participate in the counselling process wisely and smartly and wait till the last round of the counselling process. You will definitely get a seat. Best of luck.

I am sorry to say, it's not possible to get an NIT seat at this percentile. I myself have gotten 85 percentile and find it difficult to get a seat at even IIITs. Considering your boards marks, you may get into a state university or try for private colleges in your city instead.

Yes, you can participate for both the places at the same time. Because they both have different counseling methods so this will not be any issue.

No, because you have done BE, whereas cement technology is a part of chemical.
