Bangalore University — examination date

This is to inform you that due the post ponded dates of may-june 2019 examination, many students are facing losses. I am a north indian and studying under bangalore university and barely get to go home. My exam was supposed to get over on 18th june but now has been post ponded to 22nd june. I have to cancel all the tickets which were booked for heading home and planned holidays - the non-refunfable tickets. Who is liable for that? Who is going to pay for that?
I kindly request you not to extend the dates for examinations. Take it on any sundays, we don't mind. But extend of dates would be great loss to us. I hope you consider my point of view.
