With a COMEDK rank of 56,000, free seats in top colleges are unlikely. But you may get admission in private colleges like:

Dayananda Sagar College (Civil)

RNS Institute (Civil)

NMIT (Civil)

SDM College (Civil)

Acharya Institute (Civil)

Choose core branches like Civil or Mechanical for better chances. Attend all counseling rounds and be open to self-financed seats.
