Interest in colleges

So, I'm in my 3rd year of high school. Which means "Time to shop for colleges!!!" Hopefully you all can read the sheer happiness within that statement because honestly, I'm worrying my butt off. Back in September I visited Columbia and was just in awe. There was something there that just made me feel like there is something in life that I have to aspire to and this is school that will allow you to achieve that goal the most. And now almost two months later that is my first choice school. Next month I'm planing a trip up to Fordham to see what they're all about. But in the mean time I have to focus on the SAT and not getting anything less than an A in all of my classes.
