Hello Lakshman,

So, as seen through your information, your ST percentile is 61.

See, with this information it is very hard to predict which colleges you may get under JoSAA rank as you have not provided the ST Rank .

However from the previous trends of cutoffs at various NITs it is imperative that you may not be able to get a seat in any NITs/SPA/GFTIs offering B.Arch degree under JoSAA.

Here's a list of all cutoff for NITs yearwise

You can also check which colleges you may get under this rank using the Careers360 college predictor tool given below link

Meanwhile, it is advised to you to kindly also take part in various other state level counselling like that of punjab, rajasthan etc. Or try to go through a private colleges which accept JEE Main rank for admission.

Also do take part in JoSAA 2020 counselling.

Good Luck !
