Hello,





No there's no problem if you don't study your 11th and 12th from CBSE board, you can do your intermediate with any state board of your choice. The only point of concern is that try to score atleast greater than 60% because in many colleges there is criteria that the candidate should have atleast 60% in their 12th board. Talking about JEE mains, it requires a minimum of 75% in 12th boards for getting admission into NIT'S, IIT's or GIFT'S.





Hope it helps.
