Why is the JEE Main taking place twice ?


The best thing about conducting JEE Main in multiple sessions
is that a student cannot lose one year if for some reason
they are not able to perform well as they will now have two chances
to perform well in the exam.
In the first attempt, students get the first experience of taking the
JEE Main exam and get to know their mistakes which they can
improve in the second attempt. Candidates can choose the ideal time
to attempt the exam according to their level of preparation.
Candidates can appear for JEE Main 2 times to improve their score.
Candidates will have less pressure during the exam because they will
know that it is not the end and there is one more chance left. If
someone missed the examination for reasons beyond their control,
then they will not do it.
