Hello greetings

The result of JEE mains is he not yet announced and it will be the rings will be announced once both session of the JEE  main gets over therefore you will have to wait for now if you want to check the ranks vs marks of JEE main 2018 then you can check but it will not be beneficial this year because there are many shifts and its course will be normalised with respect to your shift there for this year only percentile is course will matter rather than the solute marks.

Hope this helps all the best
