Hello Spandan, Greetings!

Let me help you.

Actually the marks vs rank and marks vs percentile vary ever in JEE Mains due to various factors such as varying difficulty and competition.

On a rough note, you must aim for a score of 250 above, only then you will be able to get a score above 200 and then your rank would be under 4000.

The corresponding percentile would be around 99.84-99.88.

Thank you, hope this helps.
