You are nothing but a number to them. They don’t care if you succeed or fail, they already got your money and there are just too many students for them to care about any of them. They will welcome any student with the ability to pay from any country in the world, they won’t warn you that student housing is nearly impossible to find and outrageously expensive. I spent several months homeless and sleeping on friends’ couches due to the housing shortage and no one at the university cared enough to even respond to my emails asking what services were available to homeless students. They just don’t care about you or your educational pursuits, they just want your sweet sweet international tuition fees. The other big issue is that the academic standards are just all over the place, some teachers seem to be incredibly rigorous and mathematical and others entirely theoretical. Some professors have some weird grudge against helping students be prepared for the exam, it’s like they think that if you had been paying attention then you should already know everything there is to know about the subject so there is no need to review the important concepts. I just wanted to know what I needed to focus my energy on but most teachers treated me like I was asking to cheat when I asked for an old exam or practice test.
