Hello Yash,

The JEE mains April session dates have already been released. It will be held from 3rd April to 9th April 2020. However, the NIOS 2020 exam dates have not been released yet. It is expected to be announced in the month of February 2020. So, I would suggest you to keep yourself updated with the announcement online. Until then, focus on your first preference exam among these two. Also, take a note of when you have your shift for JEE mains and the date of NIOS exam. If they clash, I would suggest you to choose either one of them. But, let's hope for the best.

Good luck!

Hello,

There is zero possibility that it will clash. Boards take special care of it that it won't clash with any other national or state board exam. Don't worry about that.

There are officials who do search and look records the dates and then finalize their own. Some exams are specific and their are dates are fixed like JEE mains 1st sunday of april

Just prepare well and increase your performance as much as you can.

Hope it helps!
