Hi,

With 86 percentile you would get CRL rank of around 1,45000+. With this percentile and rank, getting in CSE Core in NITs is difficult. You can still apply for JOSAA Councelling and there you had some chance of getting NITs.

However CSE-Core in VIT Chennai is also a good option. Although with category 2, it would be costly but VIT is among the top private colleges in India.

Thanks!!
