happy to help!

The cutoff gets decided when once everyone gets to the exam and on their average score.

its a tradition off jee that :

• if the paper is tough,comparatively difficult then the cutoff would be low
• if the paper is easy,comparatively easy then the cutoff goes high
• anyways you could refer to the previous years cutoff to get an idea about the cutoff range and it’s relation with difficulty of paper
• link provides cutoffs of previous years : https://www.google.co.in/amp/s/engineering.careers360.com/articles/jee-main-cutoff%3famp

Thank you!
