VIT is one of the best private engineering most sought after colleges in India, and getting into it is a big deal.
category 1 of VIT is for the students who have to pay a low amount of fees than others and have the top 20000 rankers in it.

For VIT Chennai, the closing rank for the CSE branch was around 16000 in 2017 and 2016, while it was 33000 in the year 2015.
so there is a very inconsistent pattern.
But since you expect to have around 53-63 marks in the exam which is really good, you should expect a rank of around 8000-9500.
So, you have full chances to get CSE in the VIT Chennai and that too in category 1.
Hope it would help.
