The cutoff will likely to be published after the April session results out.You have to wait.. And prepare for the April session if you are interested to appear in that session. 

Good luck. 

Hello Tarun,

Thanks for contacting Careers360.

The National Test Agency NTA will declare the combined result of both the JEE Mains exam (1st which was held in January and 2nd which is going to be held in April) after the declaration of result of 2nd exam i.e. after April 30. The cutoffs will released along with the result. 

Hope this helps.

Good luck!!
