Hello aspirant ,

First of all congratulations for getting such a good rank in JOSAA councelling as your rank is 8924 .

Since you've mentioned that you have got civil engineering seat in nit surathkal in karnataka , but you want much better branches in the same college - nit surathkal through CSAB counselling.

So , seeing the previous year cutoff trends in CSAB round counsellings , there is high chance for you to grab a seat in cs , it , ee , eee but may be in different colleges of karnataka . If you want to take admissions in karnataka , so nit surathkal works best for you but if you want to take admission in any of your other preferred branch then you have to go for other colleges .

You can also check your admission probabilities in other private colleges , GFTI , NITS according to your rank/percentile with the help of college predictor tool here :
