If you are a junior or senior in high school, RIGHT NOW is the time to get on campus!
What do I mean?
You should visit (if you can) any Colleges or Universities you are/will/will consider applying to.
Open Houses are a great opportunity to see the campus and get a feel for the culture of the place.
What should you ask yourself?
Are the people friendly? Are they helpful? Can you see yourself living, studying, volunteering, being challenges, and getting involved there? Are your questions answered?
Visit the campus.
Get a feel for it.
Think about whether or not that is the place for you!
