Hello student you can calculate and get your rank easily by using this formula.

100-your total percentile) 869010 /100.

In your case your rank must be around 278083

As you must know that seats are very limited and admission is directly based on merit rank I'm sorry to inform you but with this rank being a candidate from obc category its difficult to get admission in any NIT CFTIS IIITS.

If you want to appear in Jee main April examination you need to apply for it the deadline of registration is extended till 12th of March 2020.

Feel free to comment if you have any doubt

Good luck
