Choosing the best college is a matter of figuring out what course you are going to take. Some colleges offer good programs for law like Yale or Harvard. Harvard is also known for its prestigious MBA program. But, if your inclinations are in IT or technology, then MIT might be the one for you.
The best way to determine the best college for you is by asking someone you know who goes to college to bring you to that college. Experience is the best teacher, and getting a personal feel of the campus and the environment could give you an idea of what the next four (or more) years of your life would be like. Some colleges allow sit ins. If you decide to accompany your college friend, then ask him or her if it's possible for you to sit in and observe how lectures are conducted.
Each college has its own distinct culture that sets it apart from the other colleges. They also have their own traditions which may or may not be to your liking. While other people go for prestige and price, I, personally would advise you to go with the one that you think would greatly benefit your goals in life. For some, college is a gruelling process that their parents or society forced them to take. For others, its a privilege that should be cherished. In the end, it would be better for you if you would decide to go on a college where you would enjoy learning. The start of your young adult life is critical and choosing the best college is the first step.
