Hey Shipra! Huge congratulations for getting such a good rank .

With such rank , you can expect a seat in many of the good colleges.And as far as CSE in Rv college of engineering, bangalore is concerned , the last year  maximum closing rank for CS branch of this college was 373 ,so if this year they do not vary so much,, then you can surely expect a seat there , otherwise not.But still you have good chances for many other colleges like

• BMS College of Engineering, Bangalore
• Ramaiah Institute of Technology, Bangalore
• PES Institute of Technology, Bangalore South Campus, Bangalore
• Dayananda Sagar College of Engineering, Bangalore
• Bangalore Institute of Technology, Bangalore
• JSS Science and Technology University, Mysuru
• BMS Institute of Technology and Management, Bangalore
• Sir M Visvesvaraya Institute of Technology, Bangalore
• The National Institute of Engineering, Mysore

Well having good hopes ,  we expect you to get a seat in RV college only .But considering the other side too , i would suggest you not to go for any of the colleges except the ones mentioned above.

Hope it helps!

Best hopes!
