Your percentile is quite low. With this you will get around 60K or 60,000 as your obc rank if we try to predict it. With some many students competing you will have a very les chance of qualifying for the advance . But I will ask you to give your best in your second attempt. Try getiing a 90+ percentille to get an easy chance to appear advance or get a good seat in  NITs or CFITs. I hope the best for you.
