For sure you will get some thing.If you apply all branches.Every year many seats will be un-filled because people opt for those branches. My personal opinion would be you got very good rank in aieee.If you have state reservation you can get very good NIT and branch.Even with out state reservation you can get in some nit's and with bits score 284 you should get either in goa or hyderabad.I personally feel drop is not a good option for you , as you have very good options available.
