Hii,Ishan,

If you have given both JEE main January and April,then if you score more than 90 in either,then you will be selected.

the cutof will be only one .candidate who has attempt only one paper then his score should be heigher or equal to the cutoff marks to qualify JEE main.

those ,who has attempt in both paper,there better score will be taken as final result.

and cutoff of JEE main paper I and JEE main Arch will be different.

Thank you
