Take this time to really explore your dreams. If there is a college fair at your school go to it, introduce yourself, shake hands, speak well and ask for a business card. You never know when you may need to speak to someone directly at at college, and this is your first point of contact. If you can't get to a college fair, go and visit the school. Call up the admissions office of that institution and request to be given a tour.
Most colleges have standard tour dates, but special arrangements are usually doable.
Next you will Apply to that school. Once you get to this point you may need to think of a Major to put on your application. Many students begin their college career this way. YOU are beginning to create YOUR OWN PATH in life. Parents, and others that are close to you, love and care for you, but may not always support your decisions.
