Hello Naveen Gokul. Thanks for contacting Careers360 and we hope we will be able to answer your query.

I would advice you to please reach at least 2 hours before the alloted exam time so that there is no problem in reaching the JEE Mains exam centre. 

There are so many students just like you who will also come to write the exam. So, expecting traffic, please reach at least 2 hours earlier.

Hope this helps you and all the best!
