<p>You have to keep in mind that, although a given school is your 1st choice, you really don't know that much about it. You know the things that high school students want to know, but in my opinion a lot of that stuff ends up not being that important. </p>
<p>The biggest issue has to do with majors. Most students switch majors at least once in their college career, and so beforehand they don't even know to compare the relative strengths of the departments (or even to check if they exist) across universities. </p>
<p>In general, high school students don't know much about college majors, in three respects. First, engineering and pre-med end up being horrible for some people and they drop it (right, it won't happen to you, we know). For example, this is particularly true for people who like engineering but know they want to go to, say, law school and realize that it's not worth the deflation to continue with engineering. </p>
<p>Second, high school students are not exposed to the wide range of majors that college offers. At my university 0 students come in as religious studiest majors, and it ends up being a relatively popular major, I'd guess at least 20 out of 750 students minimum. That's because for the most part they don't really know what the major is about. Most high schools simply don't offer courses in anthroplogy, linguistics, environmental studies, engineering, japanese, or neuroscience. I'm of course just picking at random but my point is high school doesn't give you a good perspective on what you should go into because it doesn't give you a taste of many of the possible choices. </p>
<p>Finally, the exposure you <em>do</em> get in high school often blows. My AP Econ class was a joke. I took Intermediate Microecon in college and was astonished at how different and amazing it was. Why? Probably because AP Econ teacher had a B.A. in History from Florida State and my Micro teacher had a Ph.D in Economics from UChicago. College professors are pros, high school teachers are not even members of the field who keep up with it. The quality of the faculty between high school and college is so unbelievable that you really don't know what the field is like since the field, to a large extent, consists of professors at universities and their activities. For another example, my IB "Theory of Mind" class was the closest thing I had to philosophy in high school, and it also was nothing at all like the experience I had in college. I wouldn't even call it philosophy. It was basically the teacher trying to mimic whatever it is that she thought philosophers do. Again, it was the case of B.A. in English vs. PhD in Philosophy, a more able mind, and years of research and collaborating with actual philosophers.</p>
