There are certain colleges and universities that are very hard to get into. It also does not help that there are some courses that are harder to get into than others. There are some students who are very hard on themselves. If they do not pass the exams to get to their dream school, they usually feel bad. Some will be very disappointed especially if they are not accepted into the course that they want.
Even in graduate school, this is an ongoing issue. The GPA scores have to be acceptable before they can be considered but even so, there are still so many things that need to be checked before they will be accepted.
