Hello,

There is no such minimum marks decided.Each year the level of paper changes and the cutoff hence changes.So I would suggest you to check previous years cutoff for your category to get a rough idea.You can also see the question paper of that year so that you can compare cutoff vs level of the paper.For more information you can visit:https://www.google.co.in/amp/s/engineering.careers360.com/articles/jee-advanced-cutoff/amp
