Chennai

According to your rank, you will easily get VIT-Vellore in the 2nd or maximum in the 3rd round. Suppose, if 1% you didn't get Vellore then you will get Chennai easily, but I would suggest you be focused on Vellore and don't try to go with Chennai campus of VIT.

Hi,
It's totally dependent on the college where you are applying for admission in B.Tech that whether that college wants your JEE score or not to be written in the given space. You need to ask the college authorities about what to do if you didn't take JEE Mains exam.

The scholarship only depends on your marks and the academic background.

Please use Google for this. I didn't understand the relevance of tagging PUMBA for this.

In terms of employability, both the colleges provide good placement in Computer Science branch. You can give you first preference to Hindustan institute of Technology.

There is no best coaching, because everybody likes to claim themselves as best. If you really want to prepare, please don't go to these so-called coaching centers. Instead, get in touch with any NID or CEED qualified student and take his or her feedback/guidance. Designers are generally very friendly people, you just need to ask for help. All the best.

Yes, with 72 marks in NATA and 88% marks in class 12th, you have a good chance to get admission in Chennai.
