You didn't scored very well in the exam but with your OBC I think you'll be able to get into a good NIT or IIIT but as you told you are from karnataka so let me tell you every college have this criteria of home state or other state and only some percent seats are reserved for the other state students hence the cut off are comparetively very high for outer state students though the cut offs different colleges aren't announced yet so need to wait for that but till than you can see what colleges you might get with this rank with the help of our jee main college predictor you just need to enter your rank your category,your home state and your desired branches and you're good to go and you can even have a look on previous year cut offs of NITs and other colleges. I am providing you the link for all.

Hi Sharath.

Cut offs of your home state NIT, NIT Surathkal, will be very high, as it is one of the top NITs. So, chances for you to get admision there is very less. And in the case of other NITs, you may get in some of them but you won't get a core branch in a good NIT. please go to this link to see cut off -
