Yes you can , unless you are satisfied with your score. My personal suggestion would be try securing your Target Percentile by the third JEE Main and start preparing for the Advanced Exam. Do check updates from the NTA Website and for more information do follow the link below

Hi

JEE mains 2021 will be conducted in four sessions i. e

*February session
* March session
*April session.
* May session

Now,
It totally depends upon students, if they want to  appear in all these 4 sessions of jee mains or not; so it's entirely student's choice. One is free to  appear in all the four session or only in 3 sessions or only two  sessions or even in only one session .

In short, yes you can attempt all the four sessions of JEE mains 2021

When a candidate appears in more then one  sessions then the best performance out of the  attempted sessions will be considered for admission i. e if you appear in all the 4 or 3 or 2 session of Jee mains, then your best score out of these  attempts will be considered for your  admission.

I will suggest you to give all the sessions of jee mains , so that even if you are not able to score good marks in February session, you will get an idea of the paper pattern and what kind of questions are asked and you will get to know about your weak areas and then you can work on them and can score good marks in jee mains other sessions. Good luck for your jee preparation.

To prepare well you can go for our jee program at the convenience of your home, the link for the same is provided below
