Changing shifts at MAIT is very easy and there is no need to worry about it. However, you must ask yourself these questions before shifting the batch - Did you wish to change your shift officially or did you simply want to sit and study in the classes which took place in the first shift?
However, the second option might feel better to you in comparison with the first because then you will not have to spend 10,000–12,000 and you will be able to change it within 24 hours.
For that, you will have to talk to the Dean or the HOD of the department and give them a convincing reason to accept your request. The process will be easy because it involves the simple act of communication, and wouldn't require any formality, but your reason should be plausible enough for them to grant your request.
