Dear Chitali,

For your kind information, as you have qulified the MHTCET examination, before that you have the choice to choose the stream you are going to opt and then you have to freeze your seat in the counseling rounds. As, you told you got the admission which means you have frozen your seat in the counseling round. So, it now it would be really a tough situation to get admission in another stream because the other good colleges also accept the admission of a candidate on the basis of MHTCET examination scored marks.

All you can do for now is to contact different colleges in which you are thinking to get admission in CSE, tell them your marks or rank you scored in MHTCET and a good reason to shift your stream, i hope then you'll get your answer and probably admission.

I hope that'll help you, best of luck for your further career prospects.
