Hey there,

     So you're about to spend four years of your life and tens of dollars of your parents' money and all you

really know about college is that all of your friends are going. Do you ever stop to wonder why you're going?

     Relax. You're making the right decision. First of all, you'll discover what interests you by taking courses

in many subjects. For example, it's hard to decide if you want to be a painter if you've never painted any

pictures; once you're in a drawing-room on campus, you'll know one way or the other. College is also a lot

of fun-after you graduate, you'll be working every weekday for 50 or so years. And remember that college

graduate earn about twice the income of those who never attended college.

     Finding the right college can be difficult. Fortunately, Johnson Review is here to help you every step of

the way.

     * Researching Schools. To us. the most important decision you'll make is to choose the school that really

fits you best-not the once that is the most competitive (有竞争力的) or has the best-equipped rooms.

     * Applying to School. On JohnsonReview.com, you'll find hundreds of actual college application (申请)

and links to many more.

     * Raising Your Scores. American College Test is once of the most important parts of the admission (录

取) course. It's not the most important, though and everyone needs to prepare for the best. But, if you can

do better, find the right course for better scores.

     * Paying for School. Most families need financial aid for the high cost of college. The problem is that

financial aid seems difficult to get and many families get caught up in the price of college rather than learning

the ways to get financial aid. If you really do your research, you'll learn that you can afford to attend any

college, no matter the cost.
