My precentage is 69 in 12th.my admission is conform or not

Dear Student,
Glad to inform you for most of the colleges in India you need to have a minimum of 50% in your 12th for being eligible to apply and with 69% you clearly surpass the minimum eligibility criteria. But for admissions to NITs/ IIITs/ GFTIs, candidates should have secured at least 75% marks in class 12th exam or be in the top 20 percentile in the class 12th exam conducted by the respective board. For SC/ ST candidates, the eligibility criteria is 65% marks in class XII.
Other than that your 12th marks however good or bad they may be doesn't confirms your admission in B.tech in any college in India, it may be used for selection purpose but doesn't confirms anything.
Hope this might help you.
