The way middles school pupils expect their futures in education to be differs a bit from how it really is, because most have quite unrealistic expectations.
Usually, the ones with the most realistic views are the ones that have older siblings, who have enough experience to tell them how the higher education system really works, and thus preparing them for less shock when they get there. However, the ones without older siblings, have very different, even unrealistic visions of how they expect their futures to be.
Even if these teenagers have parents who also have experience with higher education, it seems the parents do not discuss it with them unless they are almost at the age for high school. Therefore it would be better if these things are discussed and taught in middle school.
