Hello Aspirant,

As per the latest pattern of JEE-Main released by National Testing Agency there will be two attempts for JEE-Main in an year and it is upon you that in which attempt you want to appear and if you want to appear for both attempts then also you can but in that case you best score among the two scores will be considered for final result. Now the case which you have mentioned in the query that if you score 100 percentile in both the attempts, so in this case your final result will be 100 percentile there is no doubt, whichever result they will consider you are going to obtain 100 percentile as your final result.
