hi,

see if you get a seat in any stream of engineering through  the college counselling process, you will not have to pay any extra  fees, however if you go through management quota, fees are higher than regular candidates, .

according to kleee official site notification, some fees waiver scheme is available for students who get lower ranks in jee main/kleee/eamcet or good cgpa in board exam . follow the below link to know in details,

however at your rank you have less chances for electronics and communication, but decent chances in mechanical engineering branch.
