Hi Shreshta, 

May I know the reason you wish to change ?

For me to answer the question you need to tell me your rank and the category you belong to you also the name of the qualifying exam 

I will personally find colleges for you and see if you are eligible for the one you want 

Even though they may be under the same educational group, the cut offs may vary depending on various factors 

do let me know about what I have asked you 

ALL the best to you
