Lol that is a very interesting point for discussion
In fact there are many stories from third world countries of students from very financially disadvantaged backgrounds excelling against the odds and achieveing very high marks. They ultimately establish a very good life for themselves.
Obviusly in Australia there would be very few students who would fit into that category of poor. Generally speaking most students would have access to all resources and so the level of your finances wont determine your final educational outcome.
it comes down to the capacity of the student to fufill their aspirations and achieve what they set out to do..
