As a PhD student, we are allowed to have certain amount of funding from school. Last year, i don't even spend one cent for printing. No one say anything. But this year when i need some money for data collection, all school staff start complaining and blaming me spend too much. say i am a problem to everyone. even though i have only use half of my funding. The money we don't use does not come to next year. If you don't use, that's your loss. so i was wondering where the money go to after that.
