I GOT 89.6 PERCENT IN JEE MAINS, I M FROM GENERAL CATEGORY, BUT I HEARD A RULE THAT THOSE WHO ARE HAVING THEIR OWN HOUSE ARE NOT ELIGIBLE?

Hello aspirant,
Don't ever believe in such vague rules given by some stupid people . Jee mains is a national level examination and admission are done on the basis of marks you score and it doesn't have any such criteria that you should have a house or not, please don't believe in such fake information until and unless it's officially mentioned somewhere.
Hope it helps.
