Hello Anitha,

Top colleges known for B.Planning course are :

Maulana Azad National Institute of Technology, Bhopal

School of Planning and Architecture, Bhopal

School of Planning and Architecture, Vijayawada

Here, you will not be able to get neither SPA,Bhopal nor SAP,Vijaywada as the rank closes at approximately 650 according to previous trends. However, looking at the previous years closing rank you would have had a chance at  Maulana Azad National Institute of Technology if you were from home state and belonged to general category. But since you belong to SC category your rank should be much higher to get into these colleges.
