Greetings aspirant,

As per your percentile score in JEE Mains 2020 and in consideration that you belong to OBC-NCL category, you're likely to get a general merit list rank between AIR 90,700 - AIR 1,07,850 and category rank between 25,713 - 31,863. With this rank, you're not likely to get into BIT Mesra. I suggest you to try to score better in JEE Mains' April phase.  I have mentioned a college predictor link below. You can use it to predict your colleges as per your score.

College predictor link:

Hello Naminta puri,

The cut-off differs between the home state guy and other states and you didn't provided your home state and for your percentile you can calculate your rank using the formula (100-your total score)*869010/100 for jan exam and if number of candidates for the april exam increased to 1200000 the your final rank shall be (100-your total score)*1200000/100

and you need to secure around 30k to get seat in bit, meshra.

hope this answer helps.
