Hi aspirant,
See to get admission in NITs including NIT Tiruchirapalli you have to meet certain eligibility criteria apart from qualifying JEE Main Examination. And for NIT Trichy you will have to get really good rank as mentioned. Usually the basic eligibility criteria required for admission in NIT Trichy via JoSAA counselling is as under:
Though for this year this eligibility requirement has been scrapped. Let us see what happens next year. But if the above eligibility criteria are compulsory to meet then you will not be allowed to take admission unless you are in the top 20 percentile list ( which if you are from CBSE is not possible on 63 percentage).
