Can you please tell me about your category, so that I can guide you better?

In JEE mains, you need to score around 280+ if you are general category student for getting CSE.

As Admission is through Tamil Nadu Engineering Admissions (TNEA) counseling guidelines based on marks obtained in class 12th final examination.
With 762 marks, you have a good chance to get into PSNA, still you need to appear for the counselling to know the exact result.

The chances of getting into the college are good as you belong to BC category. But you still have to check with the college as every year the scores change.

You can check the previous year's category wise cutoff's (category ranks) of these and other NITs at: https://josaa.nic.in/josaaorcrarchieve/Result/OpeningClosingRankArchieveN.aspx?Year=2017.
You would get an idea of your selection.
Best of luck.

There is a vast difference.Petroleum engineering is a concentrated field but its scope in India is much more compared to chemical engineering.

Yes, sure you can get admission in NIT, Trichy at this rank.
