Answer:
The transition between school and university can not only be challenging but terrifying. This is because everything changes. Classes become more difficult, campus's get larger, and the pressure of getting through sets in. High school to University is a big jump even if you're a straight A student by the end of your senior year. University becomes a whole new world.
Some causes for students to drop-out of university is the pressure that is put onto them. With multiple classes and an overload of homework, one can only do so much. Plus the thought of them just working hard to end up failing with the amount of money they have put into their education.
