Oh come on, so you're saying you applied to university for the reason of what you can give to them? What can you realistically give a university ? I barely see any university staff in small groups, most of the teaching is done in massive groups. I hated this question "What can you do for the university?" the only thing i can do is be a damn hard worker, be intuitive, question things. I do this, but i do this anyways i always have done so im not really giving them anything that i don't expect from myself already. I pay my fees, make sure university staff get paid and the department has enough money to spend on things.
You last sentence is more than a bit rude, you're judging how good an applicant i was on two sentences. I'm not so rude to judge you and i expect the same.
