小题1:__________________
It is high school spring break season—and if you are a junior (or an overachieving sophomore), chances are you will spend a chunk of your vacation wandering around college campuses with super-enthusiastic, backwards-walking student tour guides.
“As a parent who recently went through this process, I know how stressful these visits can be for both the student and the parent,” Taylor said. “But on the flip side, they can be fun and exciting, as well as offer a great learning experience and a time to bond.”
小题2:__________________
For students who live far from schools they are interested in, but who may not have the money for personal visits, start by visiting colleges in your area that are similar to your schools of choice. For example, see first-hand how a large, public campus differs from a small private school.
小题3:__________________
Too often students will choose a college based on word of mouth or one that looks great on paper. But once they arrive, they immediately know it’s a mistake (or the right one!). There are many aspects of campus life that you can’t understand until you actually set foot on campus—such as the surrounding areas, the energy of the students and the quality of the facilities. By visiting beforehand, you’ll assure that you apply only to colleges where you’d actually want to spend four years.
小题4:_________________
To get a true feel for a campus, you should try to experience it on a typical day—when classes are in session and the campus is a buzz with activity. Try not to visit on a weekend or during the school’s spring break, if possible.
小题5:_________________
Since much of the college experience exists outside classroom walls, students should take note of the school’s immediate neighbourhood and of the available amenties in close proximity to the campus—affordable restaurants, museums, movie theatres, concert halls, and shopping areas.
