Hey Rohith,
As you said that you didn't like the college alloted to you.Going for phase 2 is a good option but, the bitter truth is that chance getting a better college is not that high.Hope you know that college seats in phase 2 are the seats remained in phase 1.The best suggestion I can give you is select your preferred colleges for phase 2 and wait for the result.If this turns your way then go for it. If not the only option left for you is Management quota.
