I see that you want to do B.arch from nit Calicut or not Trichy , whichever you get. You belong to sc category and being home State , it will be easier for you to get admission in nit Calicut. 

If I see previous year closing rank , which was around 600 in round 7. So it is possible that you will get a seat in NIT Calicut till round 6. 

But for nit Trichy your rank is too high to get admission in it. 

So you will be going in nit Calicut. 

Hope it helps.

Thank you.
