Yes you can get admission in top 6 college of Bangalore. But not in CS,IS,EC,EEE. May be you will get but in last round. And as you told that you belongs to defence quota if you have a domicile of Karnataka then only it is applicable otherwise there is no use.
Best of luck

Hi Nithin

yes you have a very good chance to get admission in some of the good colleges in Bangalore just be ready for the counselling session

thanks
