Please restructure your question. Do mention the name of university/college you wish to take admission and in which degree course so that I can clarify your doubt.

Hey Sreelakshmi

In order to join a good college you must know what you want to do in future. And then based on your career choice, you can look for prospective colleges that are good for your choice of course. There are many good colleges in every field in India, so first of all you must make the choice about your field of interest.

Thank you.

If you are in your intermediate or appear for highschool, then you can start preparing for the JEE or NEET which is your choice. 

So, you can get admission in top colleges like IITs, NITs and  IIITs .

I hope you get the answer with this one. 

Good luck  !!
