Hello Fazal,

JEE Main allows maximum three attempts per candidate. In a year a candidate can attempt JEE Main paper twice. So this is used in correlation with the original number of attempts, from 2019 onwards the total number of attempts for JEE Main will be six.

And Since you have attempted JEE Main, only twice, you have two more chances in the year 2020.( Because from 2019, JEE MAIN is conducted twice in a year).

Hopefully this helps and do comment below for any more queries.
