Hello Tejas,

For scoring 99 percentile in Jee mains is like getting a rank under 15k.

So, one need to score between 160 to 180 marks in papar of medium toughness.

Since you are talking about an easy paper,  more students would be scoring high score.

So one need to get marks between 180 to 200 to secure 99 percentile.

Hope this will help.

All the best for future.
