"Is this school for me?"
When asked this question, I think of myself and how I made this decision. It is hard to decide at such a young age where you will spend the next four years. What I found most beneficial was to make your own personal check list of what you want in a school. Once a list is made, it will be easier to pick a school that fits into what you want. Hopefully this little list will help you decide if you are making the right decision!
Distance From Home-It is very important to decide how far you would be willing to be away from home. Do you want to be in state or out of state? Close to your hometown or as far as possible. A good way to figure out what you want, is to think the logistics of every option: will you be coming home often, what is your mode of transportation home, do you have family nearby?
Campus Life-Depending on your hometown, this may contribute to your decision if you want to be in a rural area, city campus or more of a suburb "college" town. You may also want to look into what the campus offers you for living accommodations. What are the dorms like, can you park your car on campus, what are the dinning halls like, what is there to do on and off campus?
Money-Something to consider when looking at schools, is the tuition and room and board. If you can afford a school or will need to take out loans should play a big role in picking a college. If a school is willing to give you a scholarship, you should also consider this when making the final decision on a school.
What You Value-What exactly are you looking for in a school? Are you going for sports, a specific major or educational program, the different clubs or the all around college experience at a specific school? Figure out what your priorities are that you want at your school.
Have faith that you are picking the right school. Typically, when you visit the school, you will know that you want to go their or not based on the "vibe" you will feel. If you feel at home, you will probably want to make it your home for the next four years.
