Hello kartik

As per the latest news there is no such information released or any hint is given by authority regarding the percentage of boards for admission in NIT s . And as you know this type of system is already followed few years ago .

And it is sure that in 2020 there is no implementation because all the details have been decided earlier for 2020 and jee mains chance -1 has been conducted in January . So it will be unfair if anysuch things happens .

So don't worry that may be the fake news or someone just posted any wrong information .

Good luck and keep focus on your studies
