Hi aspirant,

Your questions is not Fully clear to understand.

Nevertheless, let me answer.

From last year National Testing Agency(NTA) introduced percentile system and started  taking two JEE Main paper: one in January and second one in April. The final score is calculated based on those paper in which the candidate scored more and best. Moreover, if a candidate appeared in only one paper then his/her final result will be declared based on that paper.

This year on a account of Covid19 pendemic JEE Main April was delayed and would be conducted in September.

Hope you understand and wish you all the best.
