Hello Aspirant,

It is not known yet. See two attempts of JEE-Main 2021 have already conducted in month of February and March but the April and May sessions have been postponed till further notice due to the prevailing circumstances and as of now there are no new dates, few days back NTA released a notification which states that new dates will be announced 15 days prior to the commencement of exams so we have to wait for the conditions to get under control so that the new dates can be decided.

As you are JEE-Main 2021 aspirant so you got some extra time to finalize your JEE-Main 2021 preparation so utilize this extra time in solving previous year question papers and sample papers because it will increase your numerical solving capability and also solve the papers in the prescribed time limit.
